[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). Refer also to driver documentation for the particular URIs supported." ... @Cole: I've merged your comment - could you please (N)ACK that?

[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
by Dave Allan 17 Nov '09

17 Nov '09

It would be helpful to have an API that exposes the relationship between SR IOV physical functions (PFs) and virtual functions (VFs). I'm thinking of implementing three new API calls and adding a small amount of additional information in the node device pci device capability, as in the attached patch. Let me know what you think.

[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?

[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

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

[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/

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.
