by Sebastian Greatful 30 Nov '09

30 Nov '09

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. Seems like the issue has been already reported once: http://www.mail-archive.com/libvir-list@redhat.com/msg11431.html but without any resoulution. I've tried libvirt-0.7.4 + also applied bb8d57c68a5d9601058692813c7bdaf83c3d3aff (Fix threading problems in python bindings) which seemed to me might be related but still the problem persists. here's

[libvirt] Howto store schedinfo in the domain definition
by Ralf Nyren 27 Nov '09

27 Nov '09

Hi, Is there support for storing the values accessible with eg virsh schedinfo <domain> --set param=value in the domain definition xml file? Tried to find the syntax definition for this but didn't find anything. Many thanks, Ralf

[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. It is 6AM so will not do a serious attempt at debugging this, just wanted to check if anyone had an idea before I spent more time potentially debugging stuff that is know to not work. >From dmesg: [ 986.341633] device vnet0 entered promiscuous mode [ 986.342897] virbr0: topology change detected, propagating [ 986.342902] virbr0: port 1(vnet0) entering forwarding state [ 986.380733] pci-stub 0000:09:01.0: enabling device (0000 -> 0003) [ 986.380786] pci-stub 0000:09:01.0: PCI INT A -> GSI 22 (level, low) -> IRQ 22 [ 986.422128] pci-stub 0000:09:01.0: restoring config space at offset 0x9 (was 0x0, writing 0xe3c04000) [ 986.422141] pci-stub 0000:09:01.0: restoring config space at offset 0x8 (was 0x1, writing 0x1041) [ 986.422152] pci-stub 0000:09:01.0: restoring config space at offset 0x7 (was 0x1, writing 0x1061) [ 986.422163] pci-stub 0000:09:01.0: restoring config space at offset 0x6 (was 0x1, writing 0x1051) [ 986.422174] pci-stub 0000:09:01.0: restoring config space at offset 0x5 (was 0x1, writing 0x1065) [ 986.422185] pci-stub 0000:09:01.0: restoring config space at offset 0x4 (was 0x1, writing 0x1059) [ 986.422199] pci-stub 0000:09:01.0: restoring config space at offset 0x1 (was 0x2b00000, writing 0x2b00003) [ 987.172975] assign device: host bdf = 9:1:0 [ 987.173054] deassign device: host bdf = 9:1:0 [ 987.206121] pci-stub 0000:09:01.0: restoring config space at offset 0x9 (was 0x0, writing 0xe3c04000) [ 987.206134] pci-stub 0000:09:01.0: restoring config space at offset 0x8 (was 0x1, writing 0x1041) [ 987.206146] pci-stub 0000:09:01.0: restoring config space at offset 0x7 (was 0x1, writing 0x1061) [ 987.206157] pci-stub 0000:09:01.0: restoring config space at offset 0x6 (was 0x1, writing 0x1051) [ 987.206167] pci-stub 0000:09:01.0: restoring config space at offset 0x5 (was 0x1, writing 0x1065) [ 987.206178] pci-stub 0000:09:01.0: restoring config space at offset 0x4 (was 0x1, writing 0x1059) [ 987.206192] pci-stub 0000:09:01.0: restoring config space at offset 0x1 (was 0x2b00000, writing 0x2b00003) [ 987.206225] pci-stub 0000:09:01.0: PCI INT A disabled [ 987.286791] libvirtd[3193]: segfault at 10 ip 00007f921b4546b4 sp 00007f9216e165e0 error 4 in libpthread-2.10.1.so[7f921b44a000+17000] >From GDB 06:45:32.434: error : qemuMonitorCommandWithHandler:290 : cannot send monitor command 'info cpus': Connection reset by peer 06:45:32.434: error : qemuMonitorTextGetCPUInfo:436 : internal error cannot run monitor command to fetch CPU thread info Program received signal SIGSEGV, Segmentation fault.

[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] 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? I don't always see that happening (and have an strace handy where it certainly doesn't). <aliguori> no <aliguori> well, i think they added some patches for that <aliguori> but originally, that's not how it worked <aliguori> and i think it's silly to work that way <aliguori> -incoming should mean, wait patiently for an incoming migration <aliguori> there's no point in interfacing with the monitor in the interim <mDuff> I agree that interacting may not be called for, but at least connect()ing -- if it's a UNIX socket, the other side won't be able to connect at all until qemu goes first... <aliguori> heh, well.... <aliguori> that particular race condition is addressed by -daemonize <aliguori> because that's generally true <aliguori> you don't know how long qemu will take to open the monitor <aliguori> but -daemonize makes gives you notification because it doesn't daemonize the process until you've gotten to the point where all sockets are open <aliguori> but IIRC, libvirt doesn't use -daemonize

[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. Uri should only be specified if you want to migrate over a specific interface on the remote host. For Qemu/KVM, the uri should be of the form "tcp://hostname[:port]". This does not require TCP auth to be setup between the connections, since migrate uses a straight TCP connection (unless using the PEER2PEER flag, in which case URI should be a full fledged libvirt URI).

[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

[libvirt] RFC exposing SRIOV PF<->VF relationships

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.

[libvirt] [PATCH] 504914 Xen scheduler setting problems

504914 Xen scheduler setting problems https://bugzilla.redhat.com/show_bug.cgi?id=504914 Doing virsh schedinfo rhel5u3 --cap 65535 the hypervisor does the call, but does not change the value nor raise an error. 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

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

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

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 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!

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.

Monitoring for addition and removal of devices is implemented. There is a lot of detail work in this code, so we should try to get people running it on a wide variety of hardware so we can shake out the differences in implementation between the HAL and libudev backends. I have moved the new fields in the node device capabilities to a separate patch.

[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

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

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
by Daniel P. Berrange 12 Nov '09

Sometimes getaddrinfo returns IPv4 addresses before IPv4 addresses. IPv6 sockets default to attempting to bind to IPv4 addresses too.

[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!
