[libvirt] [PATCH] Fix python error reporting for some storage operations
by Cole Robinson 07 Mar '25

07 Mar '25

In the python bindings, all vir* classes expect to be passed a virConnect object when instantiated. Before the storage stuff, these classes were only instantiated in virConnect methods, so the generator is hardcoded to pass 'self' as the connection instance to these classes. Problem is there are some methods that return pool or vol instances which aren't called from virConnect: you can lookup a storage volume's associated pool, and can lookup volumes from a pool. In these cases passing 'self' doesn't give the vir* instance a connection, so when it comes time to raise an exception crap hits the fan. Rather than rework the generator to accomodate this edge case, I just fixed the init functions for virStorage* to pull the associated connection out of the passed value if it's not a virConnect instance.

[libvirt] Improve the reliability of pty path parsing
by Matthew Booth 14 Dec '09

14 Dec '09

The following are improve the reliability of libvirt's mapping of character devices to pty paths. When qemu starts up it will output one or more lines of the form: char device redirected to /dev/pts/5 Note that the character device this refers to is not indicated, so the only way to match this up is by knowing the order they're written in. This is not a well-defined interface, and is therefore voodoo-magic. The current code works against current versions of QEMU. However, when using the -chardev syntax of newer QEMU, the output order changes (putting chardev first). The first patch works by making all character devices use -chardev if it's available. As well as being a better syntax, this makes the output of the redirection lines again match the order they're specified on the command line. The second patch uses this ordering to parse the ptys for channel devices from the log output. The third patch (almost) obsoletes the log output parsing method. If QEMU's monitor supports 'info chardev', this gives structured information about character devices, including pty mappings. The log output parsing method is still required because QEMU may not support info chardev, and because the monitor itself can be on a pty. The danger of the third patch is that it will fix errors in the log output parsing code, which may then bitrot. Matt

[libvirt] [PATCH] Suppress cgroup error message on sucess in qemudStartVMDaemon
by Ryota Ozaki 14 Dec '09

14 Dec '09

Even if qemudStartVMDaemon suceeds, an error is logged such as 'qemuRemoveCgroup:1778 : internal error Unable to find cgroup for'. This is because qemudStartVMDaemon calls qemuRemoveCgroup to ensure that old cgroup does not remain. This workaround makes sense but leaving an error message may confuse users. This patch simply adds an option to suppress the error log if not needed. --- src/qemu/qemu_driver.c | 16 +++++++++------- 1 files changed, 9 insertions(+), 7 deletions(-) diff --git a/src/qemu/qemu_driver.c b/src/qemu/qemu_driver.c index a4a87ac..84ee942 100644 --- a/src/qemu/qemu_driver.c +++ b/src/qemu/qemu_driver.c @@ -1763,7 +1763,8 @@ cleanup: static int qemuRemoveCgroup(virConnectPtr conn, struct qemud_driver *driver, - virDomainObjPtr vm) + virDomainObjPtr vm, + int quiet) { virCgroupPtr cgroup; int rc; @@ -1773,9 +1774,10 @@ static int qemuRemoveCgroup(virConnectPtr conn, rc = virCgroupForDomain(driver->cgroup, vm->def->name, &cgroup, 0); if (rc != 0) { - qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR, - _("Unable to find cgroup for %s\n"), - vm->def->name); + if (!quiet) + qemudReportError(conn, NULL, NULL, VIR_ERR_INTERNAL_ERROR, + _("Unable to find cgroup for %s\n"), + vm->def->name); return rc; } @@ -2142,7 +2144,7 @@ static int qemudStartVMDaemon(virConnectPtr conn, return -1; /* Ensure no historical cgroup for this VM is lieing around bogus settings */ - qemuRemoveCgroup(conn, driver, vm); + qemuRemoveCgroup(conn, driver, vm, 1); if ((vm->def->ngraphics == 1) && vm->def->graphics[0]->type == VIR_DOMAIN_GRAPHICS_TYPE_VNC && @@ -2327,7 +2329,7 @@ cleanup: VIR_FREE(vm->def->seclabel.label); VIR_FREE(vm->def->seclabel.imagelabel); } - qemuRemoveCgroup(conn, driver, vm); + qemuRemoveCgroup(conn, driver, vm, 0); if ((vm->def->ngraphics == 1) && vm->def->graphics[0]->type == VIR_DOMAIN_GRAPHICS_TYPE_VNC && vm->def->graphics[0]->data.vnc.autoport) @@ -2416,7 +2418,7 @@ static void qemudShutdownVMDaemon(virConnectPtr conn, qemuDomainReAttachHostDevices(conn, driver, vm->def); retry: - if ((ret = qemuRemoveCgroup(conn, driver, vm)) < 0) { + if ((ret = qemuRemoveCgroup(conn, driver, vm, 0)) < 0) { if (ret == -EBUSY && (retries++ < 5)) { usleep(200*1000); goto retry; -- 1.6.5.2

[libvirt] Segmentation fault when shutting down VMs
by Thomas Treutner 10 Dec '09

10 Dec '09

Hi, I'm facing another problem with latest git. This happens regularly when shutting down VM(s): http://pastebin.com/m4ef1d93f It doesn't depend on which or how many VM is/are shut down, or if I have a VNC connection to a VM that is shutting down. Sometimes after a segv, I get this: http://pastebin.com/m5260bf21 It seems to me that libvirt tries to query a qemu monitor that is no longer alive? kr,tom

[libvirt] [PATCH] Add virBufferFreeAndReset() and replace free()
by Matthias Bolte 09 Dec '09

09 Dec '09

Replace free(virBufferContentAndReset()) with virBufferFreeAndReset(). Update documentation and replace all remaining calls to free() with calls to VIR_FREE(). Also add missing calls to virBufferFreeAndReset() and virReportOOMError() in OOM error cases. --- HACKING | 5 ++- daemon/libvirtd.c | 6 ++-- docs/hacking.html.in | 7 ++-- src/conf/capabilities.c | 4 ++- src/conf/domain_conf.c | 11 +++--- src/conf/interface_conf.c | 5 +-- src/conf/network_conf.c | 4 +-- src/conf/node_device_conf.c | 4 +-- src/conf/secret_conf.c | 4 +-- src/conf/storage_conf.c | 8 ++--- src/esx/esx_driver.c | 3 ++ src/esx/esx_vi.c | 10 ++--- src/esx/esx_vi_methods.c | 68 +++++++++--------------------------- src/esx/esx_vmx.c | 11 +----- src/libvirt_private.syms | 1 + src/node_device/node_device_udev.c | 1 + src/opennebula/one_conf.c | 3 +- src/openvz/openvz_conf.c | 8 +++-- src/openvz/openvz_driver.c | 3 +- src/phyp/phyp_driver.c | 5 +-- src/qemu/qemu_conf.c | 39 ++++++++++++++------- src/qemu/qemu_driver.c | 5 ++- src/security/virt-aa-helper.c | 9 +++-- src/storage/storage_backend.c | 3 +- src/uml/uml_conf.c | 4 +-- src/util/buf.c | 13 +++++++ src/util/buf.h | 1 + src/util/conf.c | 5 ++- src/util/logging.c | 8 +++- src/util/qparams.c | 1 + src/xen/xend_internal.c | 14 +++++--- src/xen/xm_internal.c | 19 +++++----- tools/virsh.c | 4 +- 33 files changed, 146 insertions(+), 150 deletions(-) diff --git a/HACKING b/HACKING index 548e2a0..3fb1113 100644 --- a/HACKING +++ b/HACKING @@ -293,10 +293,11 @@ eg typical usage is as follows: ... virBufferAddLit(&buf, "</domain>\n");

[libvirt] [PATCH 0/3] fix migration of paused vms
by Paolo Bonzini 08 Dec '09

08 Dec '09

From: Paolo Bonzini <pbonzini(a)gnu.org> This is yet another try on fixing migration of paused vms. Since the driver-only solution didn't work out, I'm now fixing it directly in libvirt.c. The first two patches are the same as for the previous series. The first is a bugfix for failed migration for the QEMU driver; the second adds a "virsh migrate --suspend" option to leave the VM not running on the destination machine. As in the previous version of the patch, --suspend/VIR_MIGRATE_PAUSED is the bulk of implementing the new feature. I just query the domain state and, if it is paused, I implicitly add the VIR_MIGRATE_PAUSED flag to the migration. This is the third patch. I thought about transmitting the state in the end (since it works well if VIR_MIGRATE_PAUSED is passed only to MigrateFinish and not to MigratePerform), but I don't think it's a good idea to commit it now as it's basically untestable. It's in the fourth patch, but if you want it now and think the approach is sound, tell me and I'll test it more heavily.

[libvirt] [PATCH 00/14] Introduce support for the JSON based QEMU monitor
by Daniel P. Berrange 07 Dec '09

07 Dec '09

This is an updated series fully implementing the new QEMU monitor protocol based on JSON instead of plain text. I previously posted a proof of concept here http://www.redhat.com/archives/libvir-list/2009-November/msg00098.html Since that time, the QEMU side is actually working, so I've been able todo a real impl for libvirt now & also test it. I threw out the JSON library code I used last time, since it turned out to be quite unreliable code. Instead I'm using YAJL which is a much nicer library & integrates with libvirt very nicely.

[libvirt] [PATCH 0/2] Xen: Add support for interface model='netfront'
by Jiri Denemark 04 Dec '09

04 Dec '09

Xen HVM guests with PV drivers end up with two network interfaces for each configured interface. One of them being emulated by qemu and the other one paravirtual. As this might not be desirable, the attached patch provides a way for users to specify that only paravirtual network interface should be presented to the guest. The configuration was inspired by qemu/kvm driver, for which users can specify model='virtio' to use paravirtual network interface. The patch adds support for model='netfront' which results in type=netfront instead of type=ioemu (or nothing for newer xen versions) in guests native configuration. Xen's qemu ignores interfaces with type != ioemu and only paravirtual network device will be seen in the guest. Four possible configuration scenarios follow: - no model specified in domain's XML - libvirt will behave like before this change; it will set type=ioemu for HVM guests on xen host which is not newer than XEND_CONFIG_MAX_VERS_NET_TYPE_IOEMU - covered by existing tests - PV guest, any model - no functional change, model is passed as is (and ignored by the hypervisor) - covered by existing tests (e.g., *-net-e1000.*) - HVM guest, model=netfront - type is set to "netfront", model is not specified - covered by new *-net-netfront.* tests - HVM guest, model != netfront - type is set to "ioemu", model is passed as is - covered by new *-net-ioemu.* tests The fourth scenario feels like a regression for xen newer than XEND_CONFIG_MAX_VERS_NET_TYPE_IOEMU as users who had a model specified in their guest's configuration won't see a paravirtual interface in their guests any more. On the other hand, the reason for specifying a model is most likely the fact that they want to use such model which implies emulated interface. Users of older xen won't be affected at all as their xen provides paravirtual interface regardless of the type used. In previous version of this patch, I used "xenpv" instead of "netfront" as it looked more like kvm/qemu's virtio. However, you can find several tips how to force PV network interface for HVM guest by using type="netfront" so I changed it to conform with those tips. It also matches guest's driver name used for that device.

[libvirt] Move esxVMX_IndexToDiskName to util.c
by Matthias Bolte 03 Dec '09

03 Dec '09

I needed the inverse function to virDiskNameToIndex() for the ESX driver and added it to esx_vmx.c. The pending VirtualBox 3.1 patch needs disk index to disk name mapping too. So I want to move esxVMX_IndexToDiskName() to util.c. esxVMX_IndexToDiskName() handles indices up to 701. This limit comes from a gap in the disk name to disk index mapping of virDiskNameToIndex(): sdzy -> 700 sdzz -> 701 sdaaa -> 728 sdaab -> 729 This line in virDiskNameToIndex() causes this gap: idx = (idx + i) * 26; It can be fixed by altering this line to: idx = (idx + (i < 1 ? 0 : 1)) * 26; But this change breaks compatibility for indices > 701. So, I made two patches for either option and ask you for comments. Matthias

[libvirt] Eventtest unit test failure
by Soren Hansen 01 Dec '09

01 Dec '09

Hi, guys. I've changed the libvirt package in Ubuntu to run the test suite with every build. However, on our build daemons, the eventtest unit test seems to almost[1] consistently fail. You can see an example build log here: http://launchpadlibrarian.net/36196282/buildlog_ubuntu-lucid-amd64.libvirt_… Does this look familiar to anyone? Any idea what might be causing this? FWIW, I cannot reproduce it locally, so it's likely environmental, but at this point, I don't really know where to begin to look.

[libvirt] how do I stop libvirt futzing with my network configuration?
by Nix 30 Nov '09

30 Nov '09

So I have an existing QEMU/KVM setup with networks connected to a bridge which is routed/forwarded to the host's other interfaces. I'm trying to switch to administering at least *some* of its VMs through libvirt (probably not all as I use QEMU snapshots extensively for some of them and libvirt doesn't support that yet, if ever). So libvirt has to be able to start guests connected to a particular host bridge, and give them appropriate IP addresses. I thought it was easy to teach libvirt about this: spindle:/etc/libvirt/qemu/networks# cat /etc/libvirt/qemu/networks/default.xml <network> <name>default</name> <uuid>ee573497-1d74-473b-a2cb-9916229209b8</uuid> <forward mode='route'/> <bridge name='vm-net' stp='on' delay='0' /> <ip address='192.168.20.1' netmask='255.255.255.0'> <dhcp> <range start='192.168.20.1' end='192.168.20.254' /> </dhcp> </ip> </network> However, there appears to be no way to say 'this is what the network is already like'. That network is considered 'inactive' and can't be used by any guests, and if I try to make it active, I get this: virsh # net-start default error: Failed to start network default error: cannot create bridge 'vm-net': File exists Of course it bloody can't create that bridge: it's already there, has an IP address on the host, and has the host routing packets to it. There appears to be no option to allow libvirt to assign IPs on the host... ... should I fix that, 'net-start' tries to update iptables rules! How should I put this: I do not *not not* want libvirt pissing with the firewall in any way at all. If I want firewall rules, I'll create them. But there's no way to tell it 'hands off! This network is already active, don't try to *make* it active!' ... at least, there's none in the documentation, and there's none in the code that I can see. Or is there?

Or just add it to the VMs XML <interface type='bridge'> <mac address='52:54:00:4f:0a:76'/> <source bridge='br0'/> </interface> Works like a charm and there's certainly no configuration in libvirt for this interface, ie. nothing in /var/run/libvirt/network, and *nothing* set up in Virt Manager under "Host Details->Virtual networks You do need to make sure that you disable netfilter on the bridge or setup the appropriate iptables rules ( see http://wiki.libvirt.org/page/Networking#Bridged_networking_.28aka_.22shared…) > So as far as I can tell, if you don't want libvirt creating all your > bridges for you, you may as well give up hope of using virt-manager, or > start hacking all this stuff out of the source. > > I hoped I could use libvirt in conjunction with raw qemu.

[libvirt] [PATCH v2] Disk- and Controller Hotplug
by wolfgang.mauerer＠siemens.com 30 Nov '09

30 Nov '09

Hi, this is the second revision of a patch series to improve disk hotadd support for libvirt. It focuses on the qemu backend, but is naturally designed to be compatible with other backends as well. The objective is two-fold: 1.) Split off controller from disk handling. This is done by introducing a new domain element <controller> that is used to describe disk controllers. Support for hotplugging such controllers is added. Support to reference controllers by name is also included. 2.) <disk>s can now be associated with a specific controller; this is done by means of a <controller> subelemnt for disks. This patch addresses the questions that were raised during the review of the initial submission, massages the code by fixing some whitespace issues, gets static controller configurations to work, and adds documentation. Notice that in contrast to the first submission I did not include the patch that adds support for disk- and controller hot_remove_. Since the qemu codebase is still in bit of a flux wrt. the necessary patches required for this functionality, it will reappear some time later as a separate submission.

The options I used to build is ./autogen.sh --prefix=/usr --sysconfdir=/etc --localstatedir=/var --without-xen --with-qemu --with-qemu-user=oneadmin --with-qemu-group=oneadmin --without-uml --without-vbox --without-openvz --without-lxc Please note that I have specified qemu user and group to be non-root. So far the libvirtd service and virsh both seem to work fine but I have a few issues 1. Before running "virsh create", the image belongs to user oneadmin. During the run, it still does. But the as soon as I shutdown/destroy the instance, the image ownership changes to -rw-rw—— 1 root root I don't understand why. Is this a bug? 2. From the documentation at http://libvirt.org/drvqemu.html, the directories /var/run/libvirt/qemu/, /var/lib/libvirt/qemu/ and /var/cache/libvirt/qemu/ must all have their ownership set to oneadmin:oneadmin. However, mine are still set to root:root and it does not seem to affect the running of libvirt/qemu/kvm. For example, oneadmin@test2:~$ ls /var/run/libvirt/qemu -la total 8 drwxr-xr-x 2 root root 80 2009-11-27 13:22 . drwxr-xr-x 3 root root 100 2009-11-27 13:07 .. -rw------- 1 root root 4 2009-11-27 13:22 client.pid -rw------- 1 root root 1250 2009-11-27 13:22 client.xml 3. The libvirtd service still shows the warning message: warning : qemudStartup:904 : Unable to create cgroup for driver: No such device or address I read from earlier posts that the --without-lxc option should get rid of this message. Thank you for your help. -- Shi Jin, PhD

[libvirt] About node device enumeration problem
by ajia 30 Nov '09

30 Nov '09

Hi all, I saw two sets of node device enumeration implementation in libvirt-0.7.4 source code: 1.libudev implementation 2.HAL-based implementation I want to know which kind is used in libvirt.if both are used, which kinds solution is better? in my opinion,their abstract layer is different,HAL-based implementation may be flexible, by contrast, libudev implementation may be with better performance.whether plan to merge them or reserve a kind of implementation? thank you very much.I would be most grateful for any response . Best Regards, Alex Jia

I can easily attach a disk using the following command in virsh to a linux guest: attach-disk mydomain /dev/vg0/somethnig vdb Hwoever when I try the same to a freebsd based guest it doesnt show up under /dev. I hvae tried to substitude vdb with vda1 and all sorts of other things to no avail. How can I attache a disk to my freebsd guest? best regards, Seb

[libvirt] strange problem only if /usr/sbin/libvirtd is named
by Shi Jin 29 Nov '09

29 Nov '09

Hi there, I am having a very strange problem. I have built a git libvirt for our servers running ubuntu 9.10. The same built works on all servers but one, which gives error information: 21:08:58.827: error : qemudStartup:926 : unable to set ownership of '/var/lib/libvirt/qemu' to user 400:400: Operation not permitted 21:08:58.827: error : qemudStartup:932 : unable to set ownership of '/var/cache/libvirt/qemu' to 400:400: This is because I used the --with-qemu-user and --with-qemu-group options in building libvirt. After hours of debugging, I figured out the problem: as long as the service binary is not named /usr/sbin/libvirtd, I don't have the above errors. For example, I can rename the binary as /usr/sbin/libvirtd.1 or copy it to anywhere else and it works. I am wondering if there is anything so special about this /usr/sbin/libvirtd file name. Also, it is so strange that it works for all other almost identical servers but this particular one. I appreciate your help. -- Shi Jin, PhD

[libvirt] saving domains causes stucks all other commands
by Nikola Ciprich 28 Nov '09

28 Nov '09

Hi, I noticed that using libvirt to save running KVM domain (ie using virsh save ...) causes all other attempts to connect to libvirt and do something to hang till the save finishes.

[libvirt] Problem in handling fast prints from QEMU to stderr
by Saul Tamari 26 Nov '09

26 Nov '09

Hi, I think I spotted a bug in the way libvirtd handles stderr output from QEMU VMs. When starting a VM and QEMU outputs too much output data to stderr (during a given time period), libvirtd will fail and report the following error to /var/log/messages: libvirtd: 13:44:40.695: error : internal error Out of space while reading console log output I looked at the libvirt code a bit and it seems like the stderr-handling code (I think its in qemudReadLogOutput()) is time-dependent and if a 4K buffer overflows it will stop running this VM. As a workaround I added some usleep(250000) near the fprintf() calls (inside QEMU) and I now manage to get the VM running. Is this the way libvirtd is supposed to behave? Thanks, Saul p.s. This was tested on FC11 and libvirtd is version 0.6.2

[libvirt] [PATCH] Xen: Add support for interface model='xenpv'
by Jiri Denemark 26 Nov '09

26 Nov '09

Xen HVM guests with PV drivers end up with two network interfaces for each configured interface. One of them being emulated by qemu and the other one paravirtual. As this might not be desirable, the attached patch provides a way for users to specify that only paravirtual network interface should be presented to the guest. The configuration was inspired by qemu/kvm driver, for which users can specify model='virtio' to use paravirtual network interface. The patch adds support for model='xenpv' which results in type=xenpv instead of type=ioemu (or nothing for newer xen versions) in guests native configuration. Xen's qemu ignores interfaces with type != ioemu and only paravirtual network device will be seen in the guest. A possible addition to this would be to force type=ioemu for all other models which would result in only emulated network device to be provided for an HVM guest on xen newer then XEND_CONFIG_MAX_VERS_NET_TYPE_IOEMU. No type would be configured when model is missing in domains XML. If you think this is a good idea, I'll prepare a second version of the patch.

[libvirt] How do I import an old VM image to a new Install
by Michael N. Moran 25 Nov '09

25 Nov '09

First, I am a casual VM user. I have been using Fedora Core 7 on my Dell laptop for a couple of years with a single QEMU/KVM guest running Windoze XP. I recently installed Fedora 12 on a new hard disk and would like to use my old Windows VM image on the new install. Is there an easy way to do this? I tried copying the image itself (WindozeXpDisk.raw) to the new install and then (naively) looked for an import on the Virtual Machine Manager GUI. The closest that I found was the File->Restore saved machine. I tried that on my WindozeXpDisk.raw image and it failed as follows: Traceback (most recent call last): File "/usr/share/virt-manager/virtManager/manager.py", line 461, in restore_saved_callback newconn.restore(file_to_load) File "/usr/share/virt-manager/virtManager/connection.py", line 649, in restore self.vmm.restore(frm) File "/usr/lib64/python2.6/site-packages/libvirt.py", line 1420, in restore if ret == -1: raise libvirtError ('virDomainRestore() failed', conn=self) libvirtError: operation failed: image magic is incorrect I *can* mount the image using kpartx et. al like this; sudo kpartx -av /var/virt/WindozeXpDisk.raw add map loop1p1 (253:2): 0 31101777 linear /dev/loop1 63 sudo mount -t ntfs /dev/mapper/loop0p1 ./mnt Any clues would be helpful. thank you, mike

[libvirt] crash in libvirtd when assigning PCI device (storage controller)
by Terje Marthinussen 25 Nov '09

25 Nov '09

Compiled libvirt and friends from todays sources on ubuntu 9.10. Was playing around with vt-d and while my MB works fine with ESXi 4, I got some permission issues when I tried the KVM and virt-manager included from ubuntu so I just gambled and compiled everything from latest sources. Things seems to work fine in a normal use case, but if I a PCI device such as a storage controller, libvirtd will get a sigsev. I got the onboard Intel Sata, a PCI Sil Sata card as well as an Areca Raid controller in this machine. I have not tried the Intel Sata device as I am booting from that, but both the other devices causes sigsev. I am sure assigned an intel network card a bit earlier and it actually worked (well, the VM started to boot at least and entered win7 installation without libvirtd crashing), but when I tested that again now, seems like the ethernet card causes the same problem.

[libvirt] [PATCH 0/2] Add MAC filtering to qemu
by Gerhard Stenzel 24 Nov '09

24 Nov '09

The following series of patches is a prototype implementation of a ebtables based MAC address filter. I hope to have addressed all the previous comments. At the moment, some defaults are set when libvirtd starts and when a domain is started or destroyed. The plan is to extend this filter capability to the API level and virsh command level. The plan is also to add more filtering features like VLAN filtering and QoS filtering.

[libvirt] virt-manager and messages in /var/log/messages
by Chandru 23 Nov '09

23 Nov '09

Apologies if this has been already discussed. While using virt-manager to create a vm-guest we see the following errors being logged in /var/log/messages. libvirtd: 22:40:57.675: error : Domain not found: no domain with matching name 'guest1' libvirtd: 22:42:22.039: error : invalid storage volume pointer in no storage vol with matching path libvirtd: 22:44:55.530: error : Domain not found: no domain with matching uuid While these errors are indeed harmless and we are able to create and use a vm-guest, why log them as error messages. Could we convert them into informational messages. Though they could mean errors in other scenarios, but could we tweak or change them in a way that they could be logged in as informational messages and not as error messages. A end user would not know what to do with them. Thanks, Chandru

[libvirt] Release of libvirt-0.7.4
by Daniel Veillard 20 Nov '09

20 Nov '09

Nearly as expected, but the 0.7.3 release had a missing file and some broken dependancies, so I rolled out a new release immediately. Available as usual at ftp://libvirt.org/libvirt/ The rate of changes doesn't seems to slow down, though this release is more about incremental improvements, bug fixes and cleanups than major new features: Features: - Implement a node device backend using libudev (David Allan) - New APIs for checking some object properties (Daniel P.

[libvirt] [PATCH] 514532 Fix man page, most operation are synchronous
by Daniel Veillard 20 Nov '09

As pointed in https://bugzilla.redhat.com/show_bug.cgi?id=514532 we were historically warning about operation being asynchronous in the man page but actually most operations are synchronous. I still kept a warning about domain creation and shutdown, maybe we should add a few more, but as is this is mostly correct and better than the current description IMHO Maybe we should flag formally in the description all APIs which have an asynchronous behaviour. 514532 Fix man page, most operation are synchronous * tools/virsh.pod: the man page was stating that most operations are asynchronous while in fact most of them are synchronous except domain creation and shutdown diff --git a/tools/virsh.pod b/tools/virsh.pod index 55ec64a..2986c34 100644 --- a/tools/virsh.pod +++ b/tools/virsh.pod @@ -40,12 +40,11 @@ Most B<virsh> commands require root privileges to run due to the communications channels used to talk to the hypervisor.

[libvirt] PATCH: recent qemu-kvm requires -enable-kvm flag to activate VT optimization
by Steve Yarmie 20 Nov '09

20 Nov '09

Hello, Recent qemu releases require command option '-enable-qemu' in order for the kvm functionality be activated. Libvirt needs to pass this flag to qemu when starting a domain. Note that without the option, even if both the kernel and qemu support KVM, KVM will not be activated and VMs will be slow as molasses ;) I added a check in qemu_conf.c to see if `qemu -help` emits the -enable-kvm flag, and if so, use the flag accordingly. There exists a check in src/qemu/qemu_conf.c to check for the -no-kvm flag. This check works the same way. Adding the included code will not break systems where qemu does not have the option.

[libvirt] [PATCH] Removing devicePath member from dev struct
by Dave Allan 19 Nov '09

19 Nov '09

I realized that I inadvertently added a member to the def struct to contain each device's sysfs path when there was an existing member in the dev struct for "OS specific path to device metadat, eg sysfs" Since the udev backend needs to record the sysfs path while it's in the process of creating the device, before the dev struct gets allocated, I chose to remove the member from the dev struct. I've attached a patch. An alternative would be to store the information twice, but that seems crufty to me.

[libvirt] race between qemu monitor startup and blocking migrate -incoming
by Charles Duffy 19 Nov '09

19 Nov '09

Howdy, 'yall. I'm having issues with virDomainRestore failing, particularly under load -- even in 0.7.0, when there's no need to parse through qemu's output to find the monitor PTY. Digging through strace output of libvirtd and the qemu processes it spawns, this is happening when qemu blocks on the migrate -incoming and ceases to respond to the monitor socket -- though some versions of qemu can go into this state before the monitor socket is even opened, leading to libvirt timing out either while attempting to open the monitor socket or while trying to read therefrom, and subsequently killing the qemu instance it spawned while that instance is still attempting to migrate in its old saved state. Both of qemu-0.11.0-rc1 and qemu-kvm master have some form of blocking in -incoming exec: which can prevent libvirt from successfully carrying through a resume; I have reproduced the issue (and maintain logs from strace, available on request) irrespective of the state of Chris Lalancette's "Fix detached migration with exec" and "Allow monitor interaction when using migrate -exec" patches. The qemu binaries being used _appear_ to correctly allow monitor interaction prior to -incoming exec:... completion when interactively invoked in the trivial case shown below: $ qemu-system-x86_64 \ -monitor stdio \ -nographic \ -serial file:/dev/null \ -incoming 'exec:sleep 5; echo DONE >&2; kill $PPID' \ /dev/null QEMU 0.10.91 monitor - type 'help' for more information (qemu) DONE $ ...however, whether these same binaries work as-expected when invoked from libvirt by our automated test system under load is nondeterministic. (I have yet to reproduce the issue in a low-load environment using "virsh restore"). Is someone else working on this? Is a known-good (or believed-good) libvirt/qemu pair available? What can I do to help in getting this issue resolved? Thanks! --- libvirt-0.7.0 + qemu-kvm-0.11.0-rc1 qemudReadMonitorOutput:728 : internal error Timed out while reading monitor startup output libvirt-0.6.5 + qemu-kvm-0.11.0-rc1 error : qemudReadMonitorOutput:705 : internal error Timed out while reading monitor startup output error : qemudWaitForMonitor:1003 : internal error unable to start guest: char device redirected to /dev/pts/9 libvir: QEMU error : internal error unable to start guest: char device redirected to /dev/pts/9 ^^ particularly interesting, as the above line should have been eaten by qemudExtractMonitorPath rather than emitted as error text --- <aliguori> -incoming is blocking <aliguori> you cannot interact with the monitor during -incoming <mDuff> ...shouldn't we always be opening the monitor before starting the blocking -incoming bits, though?

[libvirt] iSCSI Multi-IQN (Libvirt Support)
by Shyam_Iyer＠Dell.com 18 Nov '09

18 Nov '09

The following patch set realizes the multi-IQN concept discussed in an earlier thread http://www.mail-archive.com/libvir-list@redhat.com/msg16706.html The patch realizes an XML schema like the one below and allows libvirt to read through it to create storage pools. These XMLs when created using a virtualization manager realize unique VM to storage LUN mappings through a single console and thus opening up possibilities for the following scenarios - * possibility of multiple IQNs for a single Guest * option for hypervisor's initiator to use these IQNs on behalf of the guest Example Usages: Usage 1: VM1 - > <Init iqn1> <------------------------> <Target iqn1> <Init iqn2> <------------------------> <Target iqn1> <Init iqn3> <------------------------> <Target iqn1> <Init iqn4> <------------------------> <Target iqn1> Usage 2: VM1 - > <Init iqn1> <------------------------> <Target iqn1> <Init iqn2> <------------------------> <Target iqn2> <Init iqn3> <------------------------> <Target iqn3> <Init iqn4> <------------------------> <Target iqn4> Usage 3: VM1 - > <Init iqn1> <------------------------> <Target iqn1> VM2 - > <Init iqn2> <------------------------> <Target iqn1> Usage 4: VM1 - > <Init iqn1> <------------------------> <Target iqn1> VM2 - > <Init iqn2> <------------------------> <Target iqn2> Example XML schema for an iSCSI storage pool created -- <pool type="iscsi"> <name>dell</name> <uuid>cf354733-b01b-8870-2040-94888640e24d</uuid> <capacity>0</capacity> <allocation>0</allocation> <available>0</available> - <source> <initiator> iqnname = "<initiator IQN1>"> iqnname = "<initiator IQN2>"> </initiator> ........................................ ........................................ <host name="<iSCSI target hostname or Target IP address>" /> <device path="<iSCSI Target IQN name>" /> </source> - <target> <path>/dev/disk/by-path</path> - <permissions> <mode>0700</mode> <owner>0</owner> <group>0</group> </permissions> </target> </pool> Each initiator iqn name can be parsed to create the unique sessions. TODO: 1) Virt Manager GUI support to allow a visual mapping of iqn->storage pool -> VM and thus creating the XML for consumption by libvirt. Libvirt support added above can realize the same using virsh options. 2) option for Guest's own BIOS & initiator to use the initiator IQNs (iSCSI in Guest) a) Libvirt support to allow iqn as an attribute for a VM's XML. b) Qemu Support to allow Guest's bios & initiator to use these IQNs.

Uri may specify the hostname or IP address of the destination host as seen from the source, or uri may be a URI giving transport, hostname, user, port, etc. in the usual form.

[libvirt] migration: qemu vs. qemu+tcp at virsh vs. libvirt-java
by Thomas Treutner 18 Nov '09

18 Nov '09

Hi, I'm having a little problem when triggering (live) migration from libvirt-java (libvirt.so at client is approx. 0.7.1), I get an error that the qemu:// driver for migration URIs is not supported, only qemu+tcp:// Strange thing is, with virsh at the same client (same libvirt.so), qemu:// works. Interestingly, the error message seems to come from libvirt.so and not libvirt-java. I'd like to avoid maintaining two different URIs/drivers for normal connections and migration destinations, especially as it works flawlessly (and fast!) with virsh? Has anyone clues where this twisted-mind behaviour could come from? kr, tom

It would be helpful to have an API that exposes the relationship between SR IOV physical functions (PFs) and virtual functions (VFs).

[libvirt] PATCH 0/2]: Fix CPU affinity management for NR_CPUS > 1024
by Daniel P. Berrange 17 Nov '09

17 Nov '09

The RHEL-6 Alpha kernels have defined NR_CPUS=4096 The glibc static cpu_set_t data type used with sched_[gs]etaffinity() has been sized with # define __CPU_SETSIZE 1024 So any attempt to use sched_[gs]etaffinity() with a static cpu_set_t on a RHEL-6 kernel ends up with -EINVAL, even if the machine does not physically have > 1024 CPUs. The syscall mandates that the cpu set arg is large enough to hold entire of NR_CPUS. Fairly recent gLibc's now provide an alternative dynamically allocated cpu_set_t data type, where the app tells glibc how many CPUs it has to be able to hold. Great, except, the kernel does not tell userspace what NR_CPUS it has been compiled with. So apps have to a pick a starting size, try the sched_[gs]etaffinity() call, catch EINVAL, enlarge the cpuset, repeat, repeat, repeat until it works. This was going to be horrible to put into the qemu driver code, so I've introduced a new util/processinfo.[h,c] file providing APis for getting/setting CPU affinity that use the dynamically allocate mask libvirt defines in its public API.

Best is just to consider it's not in the allowed values The problem is that the error won't be ouput since the xend driver will then be called and raise an error error: this function is not supported by the hypervisor: unsupported in xendConfigVersion < 4 which will override the useful information from xenUnifiedDomainSetSchedulerParameters() So best is to also invert the order in which the xen sub-drivers are called * src/xen/xen_hypervisor.c: mark 65535 cap value as out of bound * src/xen/xen_hypervisor.c: reverse the order of the calls to the xen sub drivers to get the error message if needed diff --git a/src/xen/xen_driver.c b/src/xen/xen_driver.c index 4bfcce4..a7da2ec 100644 --- a/src/xen/xen_driver.c +++ b/src/xen/xen_driver.c @@ -1524,7 +1524,8 @@ xenUnifiedDomainSetSchedulerParameters (virDomainPtr dom, GET_PRIVATE(dom->conn); int i, ret; - for (i = 0; i < XEN_UNIFIED_NR_DRIVERS; ++i) { + /* do the hypervisor call last to get better error */ + for (i = XEN_UNIFIED_NR_DRIVERS - 1; i >= 0; i--) { if (priv->opened[i] && drivers[i]->domainSetSchedulerParameters) { ret = drivers[i]->domainSetSchedulerParameters(dom, params, nparams); if (ret == 0) diff --git a/src/xen/xen_hypervisor.c b/src/xen/xen_hypervisor.c index 843102a..4254bcd 100644 --- a/src/xen/xen_hypervisor.c +++ b/src/xen/xen_hypervisor.c @@ -1345,8 +1345,8 @@ xenHypervisorSetSchedulerParameters(virDomainPtr domain, } else if (STREQ (params[i].field, str_cap) && params[i].type == VIR_DOMAIN_SCHED_FIELD_UINT) { val = params[i].value.ui; - if (val > USHRT_MAX) { - snprintf(buf, sizeof(buf), _("Credit scheduler cap parameter (%d) is out of range (0-65535)"), val); + if (val >= USHRT_MAX) { + snprintf(buf, sizeof(buf), _("Credit scheduler cap parameter (%d) is out of range (0-65534)"), val); virXenErrorFunc (domain->conn, VIR_ERR_INVALID_ARG, __FUNCTION__, buf, val); return(-1); } -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] vCenter behaviour
by Glenn Bailey 17 Nov '09

17 Nov '09

Howdy, I was taking a look at libvirt for controlling a couple of vCenter clusters and noticed it will only let you login directly to an ESX host and not the vCenter server itself. You can pass the "vcenter=" command but this seems to just tell what vcenter server to use and doesn't directly access it. If you do a "list" it still just lists the devices on the given ESX host. For a quick test I modified the esx_driver.c and added the following (I am no c programmer BTW): if (STRCASEEQ(conn->uri->scheme, "esx")) { if (priv->host->productVersion != esxVI_ProductVersion_VPX25 && priv->host->productVersion != esxVI_ProductVersion_VPX40 && priv->host->productVersion != esxVI_ProductVersion_ESX35 && priv->host->productVersion != esxVI_ProductVersion_ESX40) { Which would then let me connect directly to the vCenter server and list all the vm's on it. Am I missing something? I'm new to libvirt, but all management of a ESX cluster is always done through vCenter, and not the host. Sorry if this message is redundant as I didn't see anything blaring in the archives ;-) glenn terremark

[libvirt] ESXi: libvirt python bindings
by Federico Fortini 16 Nov '09

16 Nov '09

Hi to all. I was reading a recent post titled "ESX with Python binding", and tried to test the code posted by Matthias Bolte. I was wondering if ESXi should be considered different from ESX, because as soon as i tried to connect to esxi host I've got a traceback. The exception is raised from libvirt.py line 25 and is: libvirt.libvirtError: virConnectOpenAuth() failed Any tips to go on? My purpose is to write a simple python/django web app to "manage" esxi virtual machine. Tia, Federico Fortini

[libvirt] stat() vs. access()
by Maximilian Wilhelm 16 Nov '09

16 Nov '09

Hi! While discussing some code with Matthias, we stumbled across many occurances of stat() calls within the libVirt code (virFileExists() for example) which could be implemented in a cheaper way when using access() instead of stat(), when the only purpose is to check for the existance of a file. The one thing I'm concerned about, is the question if access() does the right thing in all situations. As the manpages didn't tell anything about directories it might be worth to clarify this in advance. A simple practical test showed that access ("/path/to/dir", F_OK) seems to work as expected. Any comments on these (optimization) thoughs? Ciao Matthias and Max -- Gib Dein Bestes. Dann übertriff Dich selbst!

[libvirt] Fedora MinGW - need for *.def files
by Richard W.M. Jones 16 Nov '09

16 Nov '09

[This is just a FYI ...] Upstream binutils or gcc changed the default way that symbols are exported for cross-compiled (Fedora MinGW) DLLs. Previously all symbols were exported. Now they are only exported if they are explicitly listed in a *.def file. There are two ways that libvirt could be changed to do the right thing here. Either (probably simplest) add '-export-all-symbols' to the libtool command line. This would have to be done conditionally based on Win32 being the compilation target. Or create a *.def file. It looks like: LIBRARY libvirt.dll DESCRIPTION "libvirt foo blah" EXPORTS <<list of symbol names, one per line>> http://msdn.microsoft.com/en-us/library/d91k01sh%28VS.80%29.aspx http://msdn.microsoft.com/en-us/library/28d6s79h%28VS.80%29.aspx The LIBRARY and DESCRIPTION lines are optional. You have to add '-export-symbols libvirt.def' to the libtool command line. (It's not clear to me at the moment if you only do this for Windows or if it's safe to pass this on all platforms -- the documentation for this is very sparse). There is a third method: you can munge all the code by adding __declspec(dllexport) to all exported symbols in the header files, conditionally of course. I'm pretty sure that's the worst of all worlds. Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-top is 'top' for virtual machines.

[libvirt] [PATCH] only remove masquerade rules in NAT mode
by Guido Günther 16 Nov '09

16 Nov '09

Hi, attached patch makes sure we only remove the masquerade rules if forwardType == VIR_NETWORK_FORWARD_NAT and not if forwardType == VIR_NETWORK_FORWARD_ROUTE since we don't use them there. This fixes: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=549949 O.k. to apply? -- Guido

[libvirt] Security driver on el5
by Daniel Berteaud 16 Nov '09

16 Nov '09

Hi. I'm running libvirt (0.7.2) on a CentOS 5.4 host. It's working quite well, but only if I configure selinux in permissive mode. I've tried to build libvirt with selinux enabled, but no matter what I try, it's still disabled. After some searching, I've found that: http://article.gmane.org/gmane.comp.emulators.libvirt/12282 "- Added a configure.in check for selinux_virtual_domain_context_path() and selinux_virtual_image_context_path() and make it disable the SELinux driver if these aren't found. These functions are new on F11, so we don't want to break build on RHEL-5 & earlier Fedora." Does this means there's no way to get selinux security driver on el5 (or anything before fedora 11) ?

[libvirt] device type 'interface' cannot be attached
by Gerry Reno 15 Nov '09

15 Nov '09

I'm using libvirt 0.6.2 on F11 x86_64 and CPU supports hw virtualization. When I try to do 'virsh attach-interface ...' I get an error that the function is not supported by the hypervisor device type 'interface' cannot be attached. Is this command not supported? Or is there something special I need to do? I found it in the man page. -Gerry

[libvirt] How to keep VM definitions in sync across hosts?
by Thomas Treutner 15 Nov '09

15 Nov '09

Hi, is there any best-practice how to keep VM definitions in sync across a couple of hosts? Is it reasonable to put /etc/libvirt/qemu/ on a NFS share? Or are there better ways? How does oVirt solve that? I'm asking because I'm currently setting up a four node "cluster" with KVM and libvirt. Previously, with Xen, I used libvirt only for changing currently running VMs (setmem, migrate etc.), but with KVM, I'd like to use libvirt the way it is intented to ;-) So I assume that VM definitions are required to be available and in sync among all nodes for doing live migration. I don't want to rsync them or wrap the virsh URI edit inside a for-loop, as I assume there are better ways? I'd like to do virsh URI edit once and have the changes propagated automagically. kr,tom

[libvirt] [PATCH] fix detach-disk for inactive xen domains
by Jim Fehlig 15 Nov '09

15 Nov '09

detach-disk was not working for inactive xen domains due to lookup of device ID from xenstore. When detaching disks there is no need to use device id as device name can be used directly. Unfortunately that same is not true for network devices. In fact, AFAICT, there is no way to "hot unplug" a network device from inactive domain using xen tools. I have tested attaching/detaching disks to/from both active and inactive domains. I've also ensured no regressions in attaching/detaching network devices on active domains and attaching network devices on inactive domains. As noted above, detaching network devices from inactive domains does not work, but I'm not sure what we can do about that since xen tools themselves don't support this. Any suggestions are kindly welcomed. Oh, and I also ensured all of these scenarios work with both PV and HVM domains. Regards, Jim

[libvirt] [PATCH] esx: Fix MAC address formatting
by Matthias Bolte 15 Nov '09

15 Nov '09

VMware uses two MAC address prefixes: 00:0c:29 and 00:50:56. The 00:0c:29 prefix is used for ESX server generated addresses. The 00:50:56 prefix is split into two parts. MAC addresses above 00:50:56:3f:ff:ff are generated by a vCenter. The rest of the 00:50:56 prefix can be assigned manually. Any MAC address within the 00:0c:29 and 00:50:56 prefix can be specified in a domain XML config and the driver will handle the details internally. * src/esx/esx_vmx.c: fix MAC address formatting *

[libvirt] Entering freeze for 0.7.3
by Daniel Veillard 13 Nov '09

13 Nov '09

I think that all expected feature patches have been pushed to git head so it's time to enter feature freeze, and just do cleanup and bug fixing patches until next friday. So the plan is to get 0.7.3 out on the 20th and we then have one month before the end of year holliday season to push the following release (probably 0.7.4 as I don't see a major feature landing in next month, but we never know). so let's focuse on debug for the coming week ! happy hacking :-) Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] [PATCH 0/4] AppArmor updates
by Jamie Strandboge 13 Nov '09

13 Nov '09

Hi, The following patchset contains various cleanups for the AppArmor driver. It assumes that the patch contained in the email with the following subject is already applied: [libvirt] [PATCH] fix virt-aa-helper failure when host arch and os.type arch are different This patch was ACKed but never applied. When committing that patch, please also chmod 755 ./tests/virt-aa-helper-test. 1_aa_profile_updates.patch: Adds pulseaudio, alsa and preliminary save/restore to the example apparmor abstraction. Also allows libvirtd access to inet dgram, inet6 dgram, inet6 stream and /usr/lib/libvirt/*. 2_aa_require_absolute_path.patch: Require absolute path for dynamic added files. This is required by AppArmor and conveniently prevents adding tcp consoles to the profile. This fixes https://launchpad.net/bugs/460271. 3_aa_deny_write_to_readonly.patch: Suppress confusing and misleading apparmor denied message when kvm/qemu tries to open a libvirt specified readonly file (such as a cdrom) with write permissions. libvirt uses the readonly attribute for the security driver only, and has no way of telling kvm/qemu that the device should be opened readonly. This fixes https://launchpad.net/bugs/453335. 4_aa_driver_cleanups.patch: Implements all changes requested by DV except for getting rid of readlink(). I can't use virFileResolveLink() because it lstat()s the file and uses st.st_size to create a buffer. Unfortunately, running lstat() on /proc/self/exe results in st.st_size to be 0. The changes pass 'syntax-check'. secaatest and virt-aa-helper-test both pass (there are several problems in the test suite causing 'make check' to fail. These are all unrelated to these patches).

[libvirt] [PATCH] Fix incorrect reference counting logic in qemu monitor open
by Daniel P. Berrange 13 Nov '09

13 Nov '09

The QEMU monitor open method would not take a reference on the virDomainObjPtr until it had successfully opened the monitor. The cleanup code upon failure to open though would call qemuMonitorClose() which would in turn decrement the reference count.

[libvirt] [PATCH] Fix initscript to check daemon pidfile

The libvirtd initscript could get confused between the system and session instances of the daemon.

[libvirt] [PATCH] fix virt-aa-helper failure when host arch and os.type arch are different
by Jamie Strandboge 13 Nov '09

13 Nov '09

This is a fix for Ubuntu bug #448671[1]. virt-aa-helper's get_definition() now calls the new caps_mockup() function which will parse the XML for os.type, os.type.arch and then sets the wordsize. These attributes are needed only to get a valid virCapsPtr for virDomainDefParseString(). The -H and -b options are now removed from virt-aa-helper (they weren't used yet anyway). The patch also adds several tests and fixes another. Please also 'chmod 755 tests/virt-aa-helper-test' so it can be run with 'make check'. Thanks!

[libvirt] udev node device backend
by Dave Allan 12 Nov '09

12 Nov '09

Attached is a fully functional version of the node device udev based backend, incorporating all the feedback from earlier revisions. I broke the new capability fields out into a separate patch per Dan's suggestion, and I have also included a patch removing the DevKit backend.

[libvirt] [PATCH] Remove capng_lock() call when spawning LXC container init process
by Daniel P. Berrange 12 Nov '09

12 Nov '09

The capng_lock() call sets the SECURE_NO_SETUID_FIXUP and SECURE_NOROOT bits on the process. This prevents the kernel granting capabilities to processes with an effective UID of 0, or with setuid programs. This is not actually what we want in the container init process. It should be allowed to run setuid processes & keep capabilities when root. All that is required is masking a handful of dangerous capabilities from the bounding set. * src/lxc/lxc_container.c: Remove bogus capng_lock() call. --- src/lxc/lxc_container.c | 11 +++++------ 1 files changed, 5 insertions(+), 6 deletions(-) diff --git a/src/lxc/lxc_container.c b/src/lxc/lxc_container.c index c77d099..023d553 100644 --- a/src/lxc/lxc_container.c +++ b/src/lxc/lxc_container.c @@ -694,12 +694,11 @@ static int lxcContainerDropCapabilities(void) return -1; } - /* Need to prevent them regaining any caps on exec */ - if ((ret = capng_lock()) < 0) { - lxcError(NULL, NULL, VIR_ERR_INTERNAL_ERROR, - _("Failed to lock capabilities: %d"), ret); - return -1; - } + /* We do not need to call capng_lock() in this case.

[libvirt] Interface script for qemu/kvm determinately fails?
by Ryota Ozaki 12 Nov '09

Hi, I have a question about interface script (e.g., qemu-ifup) for qemu/kvm. qemu/kvm is dropped its all capabilities by libcap-ng before executed. So the script that is executed by qemu/kvm will fail if it executes privileged operations which are usual jobs of it. It means we cannot use <script> anymore? or I'm missing something? I think executing the script in libvirtd after creating a tap and before dropping capabilities would be a solution for that issue. Am I wrong? Thanks, ozaki-r

[libvirt] [PATCH] Add virConnectGetLibvirtVersion API
by Cole Robinson 12 Nov '09

12 Nov '09

Hi all, The attached patch adds a new API call for retrieving the libvirt version used by a connection: virConnectGetLibvirtVersion. Without this, there is currently no way to determine the libvirt version of a remote qemu connection for example. This info can be useful for feature detection/enabling/disabling. As an example, virt-install may want to use the AC97 sound device as the default sound model for new VMs. However, this was only added to libvirt's white list in 0.6.0, while the other models have been available since 0.4.3. If installing a remote guest, virt-install will want to ensure that the remote libvirtd is >= 0.6.0. Granted, the remote version could have backported the AC97 patch and virt-install would be incorrect, but better to be overly restrictive than to blindly specify AC97 and have guest creation bomb out. The 'correct' way to handle the above issue would be some combination of dropping internal whitelists from libvirt and generating them from info reported by the hypervisor, and advertising the available values in the capabilities XML. However I think this API addition makes things more manageable with little downside until a proper solution is implemented. Thanks, Cole

[libvirt] [PATCH] Finer grained migration control
by Chris Lalancette 12 Nov '09

12 Nov '09

Normally, when you migrate a domain from host A to host B, the domain on host A remains defined but shutoff and the domain on host B remains running but is a "transient". Add a new flag to virDomainMigrate() to allow the original domain to be undefined on source host A, and a new flag to virDomainMigrate() to allow the new domain to be persisted on the destination host B.

[libvirt] Windows VM doesn't start as Linux one does
by Daniel Huhardeaux 12 Nov '09

12 Nov '09

Hi, everything is in the subject. I'm running Debian SID with libvirt-bin 0.7.2-3 and virt-manager 0.8.0-2. I had 4 VMs created manually some times ago (Lenny, Ubuntu 9.04, W2k and XPHome) which I migrate to libvirt. Both Linux are booting well, both Windows not: they start but suddenly reboot. On W2K I see the white starting bannier increasing on the bottom off the screen, and when done, reboot. On XPh at the time where the booting Windows screen should appear, VM restart. The I get the famous "Windows hasn't shutdown clearly, do you want to start in safe mode ... aso) On both systems, after first fail reboot, I can try and try again, always the same. If I stared VMs manually, no problem! My start script -which started without any problem my XPHome VM- is: #!/bin/bash AUDIO="es1370" VGA="std" sudo /usr/bin/kvm -localtime -cdrom /dev/scd0 -boot c -hda /media/XP/vdisk.img -hdb /media/XP/vdisk1.img -m 512 -soundhw $AUDIO -vga $VGA\ -net nic,vlan=0 -net vde,vlan=0,sock=/var/run/vde.ctl -usb -smb public -monitor tcp:127.0.0.1:32011,server,nowait & The XML file for the same VM which fail on boot is: <domain type='kvm'> <name>XPHome</name> <uuid>26e5de74-0841-c4b3-4cc1-e0df0f93cb31</uuid> <memory>524288</memory> <currentMemory>524288</currentMemory> <vcpu>1</vcpu> <os> <type arch='x86_64' machine='pc'>hvm</type> <boot dev='hd'/> </os> <features> <pae/> </features> <clock offset='localtime'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <devices> <emulator>/usr/bin/kvm</emulator> <disk type='file' device='disk'> <source file='/media/XP/vdisk.img'/> <target dev='hda' bus='ide'/> </disk> <disk type='file' device='disk'> <source file='/media/XP/vdisk1.img'/> <target dev='hdb' bus='ide'/> </disk> <disk type='block' device='cdrom'> <source dev='/dev/cdrom'/> <target dev='hdc' bus='ide'/> <readonly/> </disk> <interface type='bridge'> <mac address='54:52:00:7a:ee:01'/> <source bridge='virbr2'/> </interface> <serial type='pty'> <source path='/dev/pts/6'/> <target port='0'/> </serial> <console type='pty' tty='/dev/pts/6'> <source path='/dev/pts/6'/> <target port='0'/> </console> <input type='tablet' bus='usb'/> <input type='mouse' bus='ps2'/> <graphics type='vnc' port='-1' autoport='yes' keymap='en-us'/> <sound model='es1370'/> <video> <model type='cirrus' vram='9216' heads='1'/> </video> </devices> </domain> ~>qemu-img info /media/XP/vdisk.img image: /media/XP/vdisk.img file format: raw virtual size: 6.0G (6442450944 bytes) disk size: 5.8G ~>qemu-img info /media/XP/vdisk1.img image: /media/XP/vdisk1.img file format: raw virtual size: 2.0G (2147483648 bytes) disk size: 268M The disk image from all Linux VMs are also raw.

[libvirt] [PATCH] Fix save and restore with non-privileged guests and SELinux
by Daniel P. Berrange 12 Nov '09

12 Nov '09

When running qemu:///system instance, libvirtd runs as root, but QEMU may optionally be configured to run non-root. When then saving a guest to a state file, the file is initially created as root, and thus QEMU cannot write to it. It is also missing labelling required to allow access via SELinux. * src/qemu/qemu_driver.c: Set ownership on save image before running migrate command in virDomainSave impl.

These patches are a re-post of Jonas Eriksson's work from a couple of months ago, that we mistakenly forgot to commit. The first patch is unchanged, apart from being adjusted for new source code layout. The second patch is changed so that it checks against the hypervisor, not Xend, since using Xend has a very serious performance impact (as much as 1 second per domain queried has been seen) Daniel

[libvirt] [PATCH] Disable IPv6 socket auto-binding to IPv4 socket

[libvirt] Mounting a bare-metal folder as a drive
by Adam Mooz 11 Nov '09

11 Nov '09

Hello List, Still working on getting the DVD drive to go, but I got another question. I'm attempting to ad a folder located on the bare-metal machine to the VM and have it appear as a drive (such as HDD), is this possible? I've looked over the documentation and it suggests this is only possible for USB devices or virtual disks, but not a folder. How would I go about adding a folder located on the bare-metal to the VM to appear as a hard drive but still be accessable to the bare metal machine? ----------------------------------------------------------------- Adam Mooz Adam.Mooz(a)gmail.com AdamMooz(a)me.com http://www.AdamMooz.com

[libvirt] Possibly deadlock with tunnelled migration
by Cole Robinson 11 Nov '09

11 Nov '09

Hi Chris (and list), Playing with TUNNELLED migration, I'm hitting an issue. Take this example: VM URI = qemu+ssh://phys1/system destconn = qemu:///system invoking virDomainMigrate with a VM from the former URI, and destconn as the latter, we will deadlock. The qemu driver would be reopening it's local qemu:///system, and eventually lock up. We should probably add some sanity checking for the URI we plan to open. Aside from that, anyone have recommendations on the best way to handle the above situation? I'm currently improving the migration support in virt-manager, and if the TUNNELLED API requires opening a URI, it makes the remote-to-local migration case a bit annoying, because we would have to require the user to provide a remote accessible URI for the local system. Thanks, Cole

[libvirt] [PATCH] phyp: too much timeout when polling socket
by Eduardo Otubo 11 Nov '09

11 Nov '09

Hello all, Since I moved to libssh2 I had noticed a weird behaviour, virsh was taking too much time to complete the operations when using phyp driver. Just found the problem, 10 seconds of timeout passed to select(). Changed to zero, since I'm just polling the socket. Actually this patch is more important than it seems, now I can write a script (using virsh) to test all the phyp features. Thanks!

[libvirt] RFC move logging initialization earlier in libvirtd
by Dave Allan 11 Nov '09

11 Nov '09

I noticed yesterday that logging gets initialized fairly far into the libvirtd startup process, so messages generated during server startup don't get logged to the same sinks that will be used for the rest of the life of the daemon. I'd like to explore moving the logging startup to an earlier point. Has this idea been explored previously? Dave

The bottom line is the test will evaluate false on some arches. unit32_t is nowhere used in libvirt code I would rather not use it, we could use size_t there since the goal is to allocate memory but I'm not 100% sure it's right, basically the test make sure we won't try to allocate more than 4G of memory in one chunk. > In src/datatypes.c at lines 335, 476, and 790, there is a test to see if uuid > is NULL.

Hum, this is the virGetxxx() functions, they lookup objects given the name or uuid, and hold big TODOs comments at the start: /* TODO search by UUID first as they are better differenciators */ /* TODO check the UUID */ And somehow I think the intend was to allow lookup only by name, with the uuid being unknown, I would think the proper fix is actually to drop the || (uuid == NULL) at the start of the function. > In src/libvirt.c at line 1122, there is an "if" statement that "ands" 0 with > the return from STREQ.

[libvirt] Mounting a raw DVD
by Adam Mooz 10 Nov '09

10 Nov '09

Hello List, I'm attempting to pass a DVD drive of a headless server into a virtual machine. So far I've managed to mount *something* into the VM, but it's being registered as a blank DVD within the VM. When I mount /dev/ dvd into the bare-metal machine it registers normally as the DVD. How do I pass physical drives into a VM and back out using libvirt?

[libvirt] [RFD] API for reporting virtual machine memory statistics
by Adam Litke 10 Nov '09

10 Nov '09

I am working on a feature that enables virtual machines to report memory statistics to the host. Examples include: free memory, number of pages swapped out/in, number of page faults, etc. This information is useful to a virtual machine manager which can use it to make memory ballooning or VM migration decisions. My implementation uses the virtio-balloon driver as a conduit for the memory info. What is the best way to expose these memory stats in libvirt? I see two possibilities. The dominfo command already queries the balloon driver so I could easily extend this command to report the additional fields. The second, and better IMO, option is to introduce a new command (dommemstat) with output similar to domblkstat. What do you think? -- Thanks, Adam

[libvirt] Libvirt & VMware using bindings?
by H Alexandre 10 Nov '09

10 Nov '09

Hi, I can see on the home page that Libvirt supports Linux virtualization platform (Xen, KVM…) but in the bindings page mentions about other languages integration (perl & java for instance). I would like to know if there is a way (using those bindings) to use standard Libvirt based code to manage VMware virtualization platform ? Thanks a lot, Regards, Alex

[libvirt] timing issues of calling virsh on the command line
by David Wilcox 10 Nov '09

10 Nov '09

Hi, I've encountered some concurrency issues when calling virsh in a script. If I try to restore a VM too soon after it's been saved, libvirtd will stop responding. As well, if I try to save a VM too soon after it's been restored, libvirtd will stop responding. At the moment, I am not using any type of wait in my program for virsh to come back. I merely let the system call run its course and I assume that virsh will return when it's done waiting. Is there any type of wait that needs to occur in order to avoid these concurrency issues? Thanks, David

[libvirt] Add support for qemu's guestfwd
by Matthew Booth 09 Nov '09

09 Nov '09

This is an update of the patchset I posted yesterday. There have been a few changes in the 4th patch, which actually adds guestfwd support: Firstly, after discussion on IRC, it was agreed that 'vmchannel' is a poor name for the collection of implementations of private host<->guest channels, because it is the name of a specific implementation. Consequently the name has been changed to just 'channel'. Secondly, I've fixed a bunch of things I noticed while adding actual vmchannel support (patches to follow separately). Lastly, I've changed the relax-ng a bit to check the precise set of attributes for guestfwd. This change is also followed up in the vmchannel support. The patch now supports the following domain XML: <channel type='pipe'> <source path='/tmp/guestfwd'/> <target type='guestfwd' address='10.0.2.1' port='4600'/> </channel> It will output the following on the qemu command line for this: -chardev pipe,id=channel0,path=/tmp/guestfwd \ -net user,guestfwd=tcp:10.0.2.1:4600-chardev:channel0 Support for -chardev is as complete as the current character device support. Because of the legacy vmchannel, there was also some confusion about whether these patches are intended for merging. These patches aren't directly related to vmchannel, and are targeted at merging.

[libvirt] [PATCH 0/6] Add internal APIs for disabling error reporting
by Cole Robinson 09 Nov '09

09 Nov '09

In testing migration, I was hitting an error in the Perform step, but this was being returned as 'Unknown Error' via virsh. The reason is that even a failed Perform will call MigrateFinish to do cleanup, but Finish will always return an NULL == error in that case, overwriting the original message. I've added internal APIs which allow temporarily disabling error reporting: any ReportError calls will log the error message, but will not overwrite the previous error and will not trigger the error callback. These APIs are then used in a few places where they are needed. Thanks, Cole Cole Robinson (6): virterror: Make a thread local error state structure virterror: Add methods to temporarily disable error reporting. qemu: migrate: Disable errors in MigrateFinish if MigratePerform failed. Disable errors if Perform failed at the libvirt.c level. qemu: Disable errors in qemudShutdownVMDaemon virterror: Log reported errors when only logging output is stderr src/libvirt.c | 5 ++ src/qemu/qemu_driver.c | 13 ++++ src/util/logging.c | 3 +- src/util/virterror.c | 143 ++++++++++++++++++++++++++++++++--------- src/util/virterror_internal.h | 2 + 5 files changed, 135 insertions(+), 31 deletions(-)

[libvirt] Status and freeze for 0.7.3
by Daniel Veillard 09 Nov '09

09 Nov '09

I think we still have some pending feature patches needed for commit before entering the 0.7.3 freeze, for example the 15 patches from Dan Berrange, I was also wondering about the udev, patch though Cole last review might indicate it's better postponing a bit. Jiri CPU flags patches may actually wait a bit, since without the associated qemu driver code they don't introduce any functional change and that will provide more time to make sure the description fits everybody's needs. I still need to review Cole patches to disable temporarily error propagation, and if I missed some features patches for review or commit please tell me because we should try to enter the freeze sometime this week. Of course the various cleanup patches like Matthias ones, or the one needed from Eduardo can and should be commited during the freeze, I have myself a number of fixes pending due to an external code review that I will have to look at this week.

[libvirt] [PATCH v2 0/2] CPU flags capabilities and domain configuration
by Jiri Denemark 08 Nov '09

Hi, These are two initial patches for CPU flags/masks support for libvirt. The first patch contains changes to schemas and describes semantics of new elements and attributes. The second patch introduces internal API functions for XML parsing and formating. Version 2 changes: - feature names moved to a 'name' attribute of 'feature' element - 'cpu' element in guest capabilities renamed as 'cpuselection' - topology attributes restricted to positiveInteger - move 'cpu' element above 'os' element in domain configuration schema - feature names restricted to [a-zA-Z0-9\-_]+ - feature names are not internally converted to lower case Jiri Denemark (2): XML schema for CPU flags XML parsing/formating code for CPU flags docs/schemas/capability.rng | 46 ++++++- docs/schemas/domain.rng | 62 ++++++++ include/libvirt/virterror.h | 1 + src/Makefile.am | 9 +- src/conf/capabilities.c | 31 ++++- src/conf/capabilities.h | 6 + src/conf/cpu_conf.c | 331 +++++++++++++++++++++++++++++++++++++++++++ src/conf/cpu_conf.h | 110 ++++++++++++++ src/conf/domain_conf.c | 15 ++ src/conf/domain_conf.h | 2 + src/libvirt_private.syms | 8 + src/util/virterror.c | 3 + 12 files changed, 620 insertions(+), 4 deletions(-) create mode 100644 src/conf/cpu_conf.c create mode 100644 src/conf/cpu_conf.h

[libvirt] [PATCH 0/9] Several bug fixes for the Power Hypervisor driver

After the last large patch has been applied I reviewed the whole driver code and found several bugs and issues. Most important memory leaks and two potential infinite loops. I've no Power Hypervisor at hand, so I can't test this changes with an actual system. Eduardo could you test this patches to make sure they don't break existing functionality? Matthias

[libvirt] 3 patches to solve bug 524280
by Daniel Veillard 06 Nov '09

06 Nov '09

Basically dnsmasq limits itself by default to 150 leases maximum. Which means we may inflict an arbitrary limit in the number of domains running on a given host https://bugzilla.redhat.com/show_bug.cgi?id=524280 The patches do 3 things: - first introduce IPv4 and IPv6 parsing routines, generally useful this could be used to double check input in other places too - then when a DHCP range is defined use those routines to parse the start and end, do some cheking and keep the range size in the structure - last when exec'ing dnsmasq compute the sum of all dhcp ranges and pass the max lease option Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

Re: [libvirt] Remote access and libvirtd

I'm working with ESX and am looking at > libvirt to see if it would be beneficial to use over the ESX SOAP API > (i'm not a SOAP fan). But in the case of remote access it doesn't appear > that libvirt will be able to help me. Well, the ESX driver is working completely remote and should therefore be helpful. The driver only uses the VI API, which practically is SOAP, to communicate with the server. If you could describe the problem you are facing a bit more precisly, one could give you some hints about how to solve this. Ciao Max -- Träume nicht von Dein Leben: Lebe Deinen Traum!

[libvirt] [PATCH 00/15] Rewrite the QEMU monitor handling v2
by Daniel P. Berrange 05 Nov '09

05 Nov '09

This is an update of this series: http://www.redhat.com/archives/libvir-list/2009-October/msg00644.html minus the patches DV already ACKd which I've merged. The main change in this series is that I've removed the change which added a RW-lock primitive in the QEMU driver. Instead I've implemented the job condition variable idea I described here http://www.redhat.com/archives/libvir-list/2009-October/msg00815.html The nice thing about this is that its actually possible to start doing timeouts of commands. This series only partially supports timeouts. A long running monitor command itself will not timeout, but if a second API call is made while someone else is using the monitor, this waiting call will timeout after 30 seconds if the monitor was not relased.

[libvirt] [PATCH] create() and destroy() support for Power Hypervisor
by Eduardo Otubo 05 Nov '09

05 Nov '09

Hello all, This patch includes a lot of changes: * I changed all references of uuid_db to uuid_table. Bigger name, but this semantic has a better understanding. * Now we have a little control of UUID generated for each partition. It's based on a table that matches UUID with LPAR's IDs, I keep it in a file that is stored in the managed system (HMC or IVM). Even having isolated functions to manipulate this file I still need to implement a way to lock it and make the operation atomic to avoid corruptions. * The XML file used in the create() function still must be improved. I used the <disk> tag to make a work around to handle storage pools. Now I ask for some help, how do I use the <pool> tag if there is no reference to it at the virDomainDef structure? I've been told that libvirt possibly would make a mini-release this week to push some major fixes on Fedora 12. Is there a little possibility to push these new phyp features too? This would be very important for the phyp project, since this functions are not just to manage partitions but manipulate them. Any comments are always welcome.

[libvirt] Guestfwd support (round 3)
by Matthew Booth 05 Nov '09

05 Nov '09

This is substantially the same as the last set. I don't think I changed patches 1 and 2 at all. Patch 3 is updated to use a virBuffer as Rich Jones recommended. Patch 4 is updated slightly for the above change, and there are a couple of other trivial tidy ups in there. Patch 5 is new. QEMU's guestfwd only supports IPv4 addresses, so we check for that. Rich Jones also noted that guestfwd is specific to QEMU. If there's a good chance this same syntax might do something simililar in a different driver, I agree that changing the name would be a good idea. However, I'm not familiar enough with other hypervisors to be able to make a call on this. If nothing else does anything similar, I'd keep the QEMU name for clarity. Matt

[libvirt] [PATCH] LXC allow container to have ethN interfaces
by Ryota Ozaki 05 Nov '09

05 Nov '09

Current implementation of lxc driver creates vethN named interface(s) in the host and passes as it is to a container. The reason why it doesn't use ethN is due to the limitation that one namespace cannot have multiple iterfaces that have an identical name so that we give up creating ethN named interface in the host for the container. However, we should be able to allow the container to have ethN by changing the name after clone(CLONE_NEWNET). The patch simply does that and numberes to ethN with ascending order from zero with no concern for what vethN is named. So say if there is one interface, its name will be eth0. Note that this patch is based on top of the prior cleanup patches. --- src/lxc/lxc_container.c | 34 ++++++++++++++++++++++++---------- src/lxc/veth.c | 31 +++++++++++++++++++++++++++++++ src/lxc/veth.h | 1 + 3 files changed, 56 insertions(+), 10 deletions(-) diff --git a/src/lxc/lxc_container.c b/src/lxc/lxc_container.c index 2419345..97b7903 100644 --- a/src/lxc/lxc_container.c +++ b/src/lxc/lxc_container.c @@ -225,26 +225,38 @@ static int lxcContainerWaitForContinue(int control) /** - * lxcContainerEnableInterfaces: + * lxcContainerRenameAndEnableInterfaces: * @nveths: number of interfaces * @veths: interface names * - * This function will enable the interfaces for this container. + * This function will rename the interfaces to ethN + * with id ascending order from zero and enable the + * renamed interfaces for this container. * * Returns 0 on success or nonzero in case of error */ -static int lxcContainerEnableInterfaces(unsigned int nveths, - char **veths) +static int lxcContainerRenameAndEnableInterfaces(unsigned int nveths, + char **veths) { int rc = 0; unsigned int i; + char *newname = NULL; for (i = 0 ; i < nveths ; i++) { - DEBUG("Enabling %s", veths[i]); - rc = vethInterfaceUpOrDown(veths[i], 1); - if (0 != rc) { + rc = virAsprintf(&newname, "eth%d", i); + if (rc < 0) goto error_out; - } + + DEBUG("Renaming %s to %s", veths[i], newname); + rc = setInterfaceName(veths[i], newname); + if (0 != rc) + goto error_out; + + DEBUG("Enabling %s", newname); + rc = vethInterfaceUpOrDown(newname, 1); + if (0 != rc) + goto error_out; + VIR_FREE(newname); } /* enable lo device only if there were other net devices */ @@ -252,6 +264,7 @@ static int lxcContainerEnableInterfaces(unsigned int nveths, rc = vethInterfaceUpOrDown("lo", 1); error_out: + VIR_FREE(newname); return rc; } @@ -757,8 +770,9 @@ static int lxcContainerChild( void *data ) if (lxcContainerWaitForContinue(argv->monitor) < 0) return -1; - /* enable interfaces */ - if (lxcContainerEnableInterfaces(argv->nveths, argv->veths) < 0) + /* rename and enable interfaces */ + if (lxcContainerRenameAndEnableInterfaces(argv->nveths, + argv->veths) < 0) return -1; /* drop a set of root capabilities */ diff --git a/src/lxc/veth.c b/src/lxc/veth.c index 8617cf7..ede85ce 100644 --- a/src/lxc/veth.c +++ b/src/lxc/veth.c @@ -247,3 +247,34 @@ int setMacAddr(const char* iface, const char* macaddr) error_out: return rc; } + +/** + * setInterfaceName + * @iface: name of device + * @new: new name of @iface + * + * Changes the name of the given device with the + * given new name using this command: + * ip link set @iface name @new + * + * Returns 0 on success or -1 in case of error + */ +int setInterfaceName(const char* iface, const char* new) +{ + int rc = -1; + const char *argv[] = { + "ip", "link", "set", iface, "name", new, NULL + }; + int cmdResult; + + if (NULL == iface || NULL == new) { + goto error_out; + } + + rc = virRun(NULL, argv, &cmdResult); + if (0 == rc) + rc = cmdResult; + +error_out: + return rc; +} diff --git a/src/lxc/veth.h b/src/lxc/veth.h index 8f2f514..8075a5e 100644 --- a/src/lxc/veth.h +++ b/src/lxc/veth.h @@ -21,5 +21,6 @@ int vethDelete(const char* veth); int vethInterfaceUpOrDown(const char* veth, int upOrDown); int moveInterfaceToNetNs(const char *iface, int pidInNs); int setMacAddr(const char* iface, const char* macaddr); +int setInterfaceName(const char* iface, const char* new); #endif /* VETH_H */ -- 1.6.2.5

[libvirt] flush guest page cache and suspend?
by Marco Colombo 05 Nov '09

05 Nov '09

Hi, I'm new to this list. I've searched the archives (and google) but I haven't found an answer. Recently I moved to CentOS 5.4, with libvirt-0.6.3 and kvm-83. They are rather new compared to 5.3 ones, so I'm still investigating on the new capabilities. My guests disk images are LV single devices, /dev/vg_virt/<guestname>, usually with two partitions, the root fs and swap space. I'd like to run backups on the node only, taking snapshots of the LVs. I'm already doing that, actually. Everything works fine, using bacula (with one minor glitch, but that's for another list). Now I wonder if it makes sense to suspend the guest before creating the snapshot: virsh suspend <guestname> lvcreate --snapshot ... virsh resume <guestname> ... perform backup ... lvremove -f <the snapshot> but thinking about it a second time it seems it doesn't add anything to the equation, the filesystem is still potentially unclean, with data to be written still in the guest page cache. The filesystem is ext3, so it's not that bad (recovers a consistent state from the journal, with standard options even data-consistent, not just metadata-consistent). Yet it's like doing a backup of a (potentially badly) crashed filesystem. While I trust the recovery step of ext3, my feeling is that it can't be 100% reliable. I have (rarely) seen ext3 crash and ask for fsck at boot, journal or not (for truth's sake, I can't rule out an hard disk problem in those cases). So, first question: does the suspend command cause a flush in the guest OS (details: both guest and node are CentOS 5.4, hypervisor is qemu-kvm)? I guess not (otherwise I won't be here). So if not, what are the options to force the sync? Ideally, there should be a single atomic 'sync & suspend'. In practice, I can think of some workarounds: ssh <guest> -c sync, or the very old-fashioned way of enabling the 'sync' user and logging in from the serial console, or issuing a sysrq-s, again on the console. I'm interested in the latter, but I wasn't able to trigger the sysrq from either 'virsh console <guestname>' or 'screen `virsh ttyconsole <guestname>` (tried minicom, too). The serial console is on pty, I'm not even sure you can generate a break on a pty. (and yes, I remembered to sysctl -w kernel.sysrq=1 on the guest). I know XEN has 'xm sysrq', but this is kvm. Is there anything similar? I think it can be done if you invoke qemu-kvm from the command line with -nographics (it multiplexes the console and the monitor lines on stdin/out, and you can send a 'break' with C-a b I think, I've never tried). So question 2): is there a way to send a sysrq-s to the guest? My fallback plan is to try and map the serial line over telnet instead of pty, and the figure out a way to send the break (which I think is part of the telnet protocol) from the command line. I'd rather not mess with telnet and local port assignment to the guests, if not necessary. My really fallback plan is to revert to shutdown/snapshot/create, which is overkill for a daily backup. Question 3): does it _really_ make sense to try and sync the guest OS page cache before taking the snapshot? Or is it just me being paranoid? For reference, here's the qemu cmdline of one of the guests: /usr/libexec/qemu-kvm -S -M pc -m 512 -smp 1 -name wtitv -uuid 445d0fe5-c1b6-4baf-a186-da1fe021158c -monitor pty -pidfile /var/run/libvirt/qemu//wtitv.pid -boot c -drive file=/dev/vg_virt/wtitv,if=ide,index=0,boot=on -net nic,macaddr=00:16:3e:57:45:4f,vlan=0,model=e1000 -net tap,fd=14,script=,vlan=0,ifname=vnet0 -serial pty -parallel none -usb -usbdevice tablet -vnc 127.0.0.1:0 and here's the xml config file for libvirt, same guest: <domain type='kvm'> <name>wtitv</name> <uuid>445d0fe5-c1b6-4baf-a186-da1fe021158c</uuid> <memory>524288</memory> <currentMemory>524288</currentMemory> <vcpu>1</vcpu> <os> <type arch='x86_64' machine='pc'>hvm</type> <boot dev='hd'/> </os> <clock offset='utc'/> <on_poweroff>destroy</on_poweroff> <on_reboot>restart</on_reboot> <on_crash>restart</on_crash> <features> <acpi/> </features> <devices> <emulator>/usr/libexec/qemu-kvm</emulator> <disk type='block' device='disk'> <source dev='/dev/vg_virt/wtitv'/> <target dev='hda' bus='ide'/> </disk> <interface type='bridge'> <mac address='00:16:3e:57:45:4f'/> <source bridge='br1'/> <model type='e1000'/> </interface> <console type='pty'> <target port='0'/> </console> <input type='tablet' bus='usb'/> <graphics type='vnc' autoport='yes'/> </devices> </domain> TIA, .TM.

[libvirt] [RFC][PATCH] LXC allow a container to have ethN named interfaces
by Ryota Ozaki 04 Nov '09

04 Nov '09

Note that this patch is not mature yet and still proof- of-concept prototype, although it actually works. Current implementation of lxc driver creates vethN named interface(s) in the host and passes as it is to a container. The reason why it doesn't use ethN is due to the limitation that one namespace cannot have multiple iterfaces that have an identical name so that we give up creating ethN named interface in the host for the container. However, we should be able to allow the container to have ethN by changing the name after clone(CLONE_NEWNET) in controller. To this end, this patch extends --veth argument of controller to be able to have two names; one is the name of a created veth, and the other is a new name. The format is: --veth veth1,eth0 --veth veth3,eth1 ... where veth1 is old name and eth0 is new one. The implementation also allows a single name, in that case, controller does not do nothing for the interface, which is the original behavior. The numbering of the new names is simply ascending order from zero. So if there is one interface, its name will be eth0. --- src/lxc/lxc_container.c | 23 ++++++++++++++++++----- src/lxc/lxc_container.h | 1 + src/lxc/lxc_controller.c | 30 ++++++++++++++++++++++++++++-- src/lxc/lxc_driver.c | 30 +++++++++++++++++++++++++----- src/lxc/veth.c | 20 ++++++++++++++++++++ src/lxc/veth.h | 1 + 6 files changed, 93 insertions(+), 12 deletions(-) diff --git a/src/lxc/lxc_container.c b/src/lxc/lxc_container.c index f4381e7..f065788 100644 --- a/src/lxc/lxc_container.c +++ b/src/lxc/lxc_container.c @@ -84,6 +84,7 @@ struct __lxc_child_argv { virDomainDefPtr config;

[libvirt] starting vm using virsh somewhat fails

I don't know if this is relevant but virsh net-list --all Name State Autostart ----------------------------------------- default inactive yes virsh net-start default error: Failed to start network default error: Failed to open file '/etc/sysconfig/system-config-firewall': No such file or directory Can this be the problem?

[libvirt] libvirt generates bad kvm command line
by Harald Dunkel 04 Nov '09

04 Nov '09

Hi folks, using this command sequence <code> export VIRSH_DEFAULT_CONNECT_URI=qemu:///system name=Testing kvmdir=/export/hdunkel/kvm hda=$kvmdir/$name/hda.qcow2 iso=/export/isos/debian-testing-amd64-netinst.iso mkdir -p $kvmdir/$name qemu-img create -f qcow2 $hda 32G virt-install --connect ${VIRSH_DEFAULT_CONNECT_URI} \ -n $name -r 1024 -vcpus=1 -f $hda -c $iso \ --network=bridge:br0 --vnc --accelerate -v \ --os-type=linux --os-variant=debianSqueeze </code> I get the famous "cdrom boot failure code 0003" error. The log file shows that libvirt generated this kvm command line: <code> LC_ALL=C \ PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin \ HOME=/root USER=root LOGNAME=root QEMU_AUDIO_DRV=none \ /usr/bin/kvm -S -M pc -m 1024 -smp 1 -name Testing \ -uuid 3a6b6b3f-84e6-6a21-a51a-2c61cf3914e2 \ -monitor unix:/var/lib/libvirt/qemu/Testing.monitor,server,nowait \ -no-reboot -boot d \ -drive file=/export/hdunkel/kvm/Testing/hda.qcow2,if=virtio,index=0 -drive file=/export/isos/debian-testing-amd64-netinst.iso,if=virtio,media=cdrom,index=1 \ -net nic,macaddr=52:54:00:3e:0b:26,vlan=0,model=virtio,name=virtio.0 \ -net tap,fd=18,vlan=0,name=tap.0 -serial pty -parallel none \ -usb -usbdevice tablet -vnc 127.0.0.1:0 -k en-us -vga cirrus </code> If I try this on the command line, then there is the same 0003 error. If I omit the if=virtio for the cdrom drive, then it boots the cd without 0003. Can you reproduce this? Is this a problem with libvirt or with the kvm module? Kernel is 2.6.31.5, i.e. kvm 0.88. libvirt is 0.7.2 Any helpful comments would be highly appreciated. Harri

[libvirt] [PATCH v2] Improve error reporting for virConnectGetHostname calls
by Cole Robinson 03 Nov '09

03 Nov '09

All drivers have copy + pasted inadequate error reporting which wraps util.c:virGetHostname. Move all error reporting to this function, and improve what we report. Changes from v1: Drop the driver wrappers around virGetHostname. This means we still need to keep the new conn argument to virGetHostname, but I think it's worth it.

[libvirt] [PATCH 0/3] IPv6 / multi address / report live config in virInterface
by laine＠laine.org 03 Nov '09

03 Nov '09

This is the 2nd iteration of this patchset incorporating danpb's suggestions. Along with a couple other minor things, the type attribute is again a required attribute, and netcf support will be omitted in the build unless you have netcf-devel-0.1.3 or greater. Since there is no netcf-devel-0.1.3 yet, I tested this by changing the appropriate strings to 0.1.2. 0.1.3 will be released "soon" (I want to try and get IPv6 address reporting in before lutter cuts another release). I just wanted to get the patches to the list early to get some visual review in case I screwed up anything new ;-) Note that (unless you're building/installing netcf from the head of git) if you try to fake out the version of netcf yourself you'll get runtime errors from virInterfaceGetXMLDesc (iface-dumpxml) due to there being no "type" attribute in the interface xml.

Let's try to push everything by this week-end and have next week as the testing and freeze time. Maybe we can squeeze everything in time, that would allow the release by the Friday 13th (unless we want to avoid that ;-) Daniel -- Daniel Veillard | libxml Gnome XML XSLT toolkit http://xmlsoft.org/ daniel(a)veillard.com | Rpmfind RPM search engine http://rpmfind.net/ http://veillard.com/ | virtualization library http://libvirt.org/

[libvirt] [PATCH] Remove redundant virFileDeletePID() call

[libvirt] [PATCH 00/21] Rewrite the QEMU monitor handling
by Daniel P. Berrange 02 Nov '09

02 Nov '09

This patch series rewrites the QEMU monitor handling almost completely. The key theme here is to move from a totally synchronous way of interacting with the monitor, to a totally asynchronous way. This allows us to handle receipt & dispatch of asychronous events from QEMU. For example a notification of a disk-full error, or VM state change. In the process of doing this re-factoring I have also dropped in basic support/infrastructure for the JSON based monitor. The basic JSON parsing/formatting is working, but this needs to wait until QEMU community finalize their monitor syntax for the new commands & what args they accept. Daniel

[libvirt] cannot get virt-manager to see VM
by Gerry Reno 02 Nov '09

02 Nov '09

I used qemu-img to create a raw image. I then create an xml file with no uuid but a new name and new mac address. Then I did a 'virsh define NEW.img'. When I do a 'virsh list --all' the new VM is there but shut_off. But this new machine does not appear in virt-manager. What do I need to do to get the new machine to appear in the list of machines in virt-manager? I want to start this machine using virt-manager. This is on F11 with libvirt 0.6.2. -Gerry

[libvirt] [PATCH] ESX: Don't automatically follow redirects.

[libvirt] [patch] Add openvzDomainSetMemoryInternal
by Yuji NISHIDA 02 Nov '09

02 Nov '09

Hi all, This patch is to set KMEMSIZE for OpenVZ. This function is used for initializing the parameter of KMEMSIZE to start container. openvzDomainSetMemory should be left for another purpose so I added new one. I think users should specify memory as kbyte ( or bigger ). --- src/openvz/openvz_driver.c | 32 ++++++++++++++++++++++++++++++++ 1 files changed, 32 insertions(+), 0 deletions(-) diff --git a/src/openvz/openvz_driver.c b/src/openvz/openvz_driver.c index f64ad1e..5c1fefa 100644 --- a/src/openvz/openvz_driver.c +++ b/src/openvz/openvz_driver.c @@ -69,6 +69,7 @@ static int openvzGetMaxVCPUs(virConnectPtr conn, const char *type); static int openvzDomainGetMaxVcpus(virDomainPtr dom); static int openvzDomainSetVcpus(virDomainPtr dom, unsigned int nvcpus); static int openvzDomainSetVcpusInternal(virConnectPtr conn, virDomainObjPtr vm, unsigned int nvcpus); +static int openvzDomainSetMemoryInternal(virConnectPtr conn, virDomainObjPtr vm, unsigned long memory); static void openvzDriverLock(struct openvz_driver *driver) { @@ -803,6 +804,14 @@ openvzDomainDefineXML(virConnectPtr conn, const char *xml) } } + if (vm->def->memory > 0) { + if (openvzDomainSetMemoryInternal(conn, vm, vm->def->memory) < 0) { + openvzError(conn, VIR_ERR_INTERNAL_ERROR, + "%s", _("Could not set memory size")); + goto cleanup; + } + } + dom = virGetDomain(conn, vm->def->name, vm->def->uuid); if (dom) dom->id = -1; @@ -1364,6 +1373,29 @@ static int openvzNumDefinedDomains (virConnectPtr conn) { return ninactive; } +static int openvzDomainSetMemoryInternal(virConnectPtr conn, virDomainObjPtr vm, + unsigned long mem) { + struct openvz_driver *driver = conn->privateData; + char str_mem[16]; + const char *prog[] = { VZCTL, "--quiet", "set", PROGRAM_SENTINAL, + "--kmemsize", str_mem, "--save", NULL }; + + /* memory has to be changed its format from kbyte to byte */ + snprintf( str_mem, sizeof(str_mem), "%lu", mem * 1024 ); + + openvzSetProgramSentinal(prog, vm->def->name); + if (virRun(conn, prog, NULL) < 0) { + openvzError(conn, VIR_ERR_INTERNAL_ERROR, + _("Could not exec %s"), VZCTL); + goto cleanup; + } + + return 0; + +cleanup: + return -1; +} + static virDriver openvzDriver = { VIR_DRV_OPENVZ, "OPENVZ", -- 1.5.3.4 ----- Yuji Nishida nishidy(a)nict.go.jp

[libvirt] Don't use private struct member names of in6_addr
by Matthias Bolte 02 Nov '09

02 Nov '09

__in6_u.__u6_addr16 is the private name for this struct member, s6_addr16 is the public one. Our buildserver revealed this problem, because for some reason the internal names are missing the __ prefix there. Matthias

[libvirt] Remaining interface state reporting issue - bond options
by Laine Stump 02 Nov '09

02 Nov '09

With the patches I sent to netcf-devel last night, along with lutter's (or DV's, take your pick ;-) netcf patch to eliminate the segfault, my patches for reporting interface info now pass make check with no errors. I believe lutter will be making a netcf release tomorrow or so, after he gets back on solid ground. There is one issue left that I'm unsure what to do about - while the xml returned from netcf for bond interfaces does list all the slave interfaces of the bond and their types (and any required info for that type), the parser for bond info in libvirt requires either an miimon or arpmode node inside the bond, eg: <interface type="bond" name="bond0"> <bond> <miimon freq="100" updelay="10" carrier="ioctl"/> <interface type="ethernet" name="eth1"/> <interface type="ethernet" name="eth0"/> </bond> </interface> I haven't been able to find a source of this information yet and, while it may be useful, I don't see it as necessary. Once again I'm proposing that we make these optional in the XML, such that this would be acceptable: <interface type="bond" name="bond0"> <bond> <interface type="ethernet" name="eth1"/> <interface type="ethernet" name="eth0"/> </bond> </interface> Once we do that, the netcf-reported state of all 4 supported interface types (ethernet, bridge, vlan, bond) will pass libvirt's parsing test.

[libvirt] Add support for qemu's guestfwd
by Matthew Booth 02 Nov '09

02 Nov '09

This series adds support for a vmchannel using qemu's guestfwd. I'll be following up with support for virtio-serial and RHEL5's vmchannel. A vmchannel is specified as: <vmchannel type='pipe'> <source path='/tmp/vmchannel'/> <target type='guestfwd' address='10.0.2.1' port='4600'/> </vmchannel> There are a couple of minor complications. Firstly, the existing chrdev structure assumes that all front-ends take only a port. There's a bit of code churn adding a second union to this struct to allow for different data for different backends. Secondly, it turns out that the existing syntax for character devices doesn't really work for guestfwd. Specifically it won't allow common options to be added. This is fixed in qemu git with the new -chardev syntax. Consequently, this patch only adds support for guestfwd using -chardev. We add detection for -chardev, and a new internal utility function to output -chardev command lines for all existing character device backends. Matt

[libvirt] [PATCH] drop the -logrotate.conf from /etc/logrotate.d/ovirt-logrotate.conf

No Fedora package uses .conf in that directory; furthermore, rpmlint protests about it: the file name should match the name of the containing rpm.
