[libvirt-users] internal error cannot parse QEMU version number
by jeremy avnet 17 Mar '10

17 Mar '10

I've seen this error a couple of times over the past month, but it's starting to happen more regularly now (perhaps since VM usage is increasing). The last few times I've seen it when trying to start a VM (virsh start domain): $ virsh start goat Connecting to uri: qemu:///system error: Failed to start domain goat error: internal error cannot parse QEMU version number in ' PC emulator version 0.11.0 (qemu-kvm-0.11.0), Copyright (c) 2003-2008 Fabrice Bellard' Running libvirt version 0.7.0-1ubuntu13.1 under Ubuntu 9.10 amd64. $ kvm --version QEMU PC emulator version 0.11.0 (qemu-kvm-0.11.0), Copyright (c) 2003-2008 Fabrice Bellard I saw this message, but it's for an older version: http://osdir.com/ml/libvir-list/2009-05/msg00192.html Any ideas on how to prevent this error? Thank you. .:. jeremy

[libvirt-users] behaviour of "virsh shutdown domainName"
by Jorge Somavilla 16 Mar '10

16 Mar '10

Hi all, I am experiencing some problems with different versions of libvirt (0.7.5 and 0.7.7), with a kvm (WinXP), host running Ubuntu 9.10, and i would like to ask you two questions: - In virsh, after running the command "shutdown domainName", what should be the final state of the domain, if the shutdown finishes correctly: "shutoff", "no-state", "inactive", or the domain shouldn't show in "list --all" (full clean-up)? - After the command "shutdown domainName", should i be able to run the command "start domainName", without first defining the domain? (i.e.: does shutdown "undefine" the domain?). In my experience 0.7.5 used to leave the shut down domains as defined, so i could run "start" right after. Testing in other hosts this doesn't work always like that, and even if the domain apparently shuts down correctly, the domain sometimes shows in "list --all", and sometimes it doesn't. With libvirt 0.7.7 the domain never shows in "list --all" after a successful shutdown, which makes me think it was a bug and it has been corrected. Am i missing anything? Any help would be much appreciated, thanks in advance. Jorge Somavilla.

[libvirt-users] Duplicate USB vendor,product specification
by Don Morrison 16 Mar '10

16 Mar '10

I studying how to attach USB devices to a KVM guest virtual machine using libvirt. Using the "vendor" and "product" to specify the source device seems like a good option since the "bus" and "device" values can change as a device is removed and re-inserted. The question I have is what should I expect to happen if I plug in two identical USB devices - so they have the same vendor/product information? There is nothing in the documentation on libvirt.org to address this case. Thanks. Don Morrison

1. Can I set the memory of a domain when it is running? 2. If the host has a total memory of 2GB and launch two VM which respectively 2GB of memory setting, because I don't have a mistake o warning? Grazie Angelo

[libvirt-users] Regarding SPICE
by anuj rampal 14 Mar '10

14 Mar '10

Hi, I have set up KVM on FC12. I was wondering if its possible to Display the VM using spice + libvirt? As in, if I can define my domain with graphics like: <graphics type='spice' port='-1' autoport='yes' listen='0.0.0.0'/> or <graphics type='spice' port='5903' ' listen='0.0.0.0'/> Thanks & Regards Anuj

[libvirt-users] Problem with libvirt migration
by Daniel Bidwell 14 Mar '10

14 Mar '10

I have two hosts, vm1 and vm2, which are both running libvirt 0.7.0. They share a common ocfs2 file system that resides on a san, and have identical network configurations. I am running qemu-kvm 0.11.0 on ubuntu 9.10 servers. I start base32 on vm1 and it comes up (it also runs fine if started on vm2). Then from vm2 I do: vm2#: virsh -c qemu://vm1/system migrate --live base32 qemu://vm2/system The migration starts and the vm2 virsh returns to the prompt. vm2 shows base32 as running and vm1 shows base32 as stopped. The console for base32 on vm2 is frozen and unresponsive. I have the debug level set to 1 on both machines. This is an excerpt from the virsh.log file from vm1: 8:19:40.772: debug : qemudDomainMigratePerform:6513 : base32: migrate reply: migrate "tcp:vm2.cc.andrews.edu:49152" 08:19:40.772: debug :

[libvirt-users] ESX support
by Jonathan Kelley 13 Mar '10

13 Mar '10

Just curious but how long has ESX support been in libvirt? Also I noticed this error when accessing one of my windows vms: error: internal error Expecting VMX entry 'scsi0.virtualDev' to be 'buslogic' or 'lsilogic' but found 'lsisas1068' Not sure whether this is an enhancement, defect, or not supported at this time. Thanks. -Jon

[libvirt-users] unable to get domain list of KVM guests from libvirt as non-root user
by Tom Georgoulias 12 Mar '10

12 Mar '10

I have a python script that monitors the guest VMs on a servers running Xen, but the script doesn't work properly on a server I just built with KVM. The script runs as a non-root user (same on all servers) and simply gathers some details on the status and names of the domains running on the host. The Xen and KVM servers are running CentOS 5.4 x86_64 and are using the same version of libvirt: libvirt-0.6.3-20.1.el5_4 libvirt-python-0.6.3-20.1.el5_4 Both Xen and KVM servers have the default libvirt.conf config file and the following /var/run/libvirt permissions: KVM: [root@kvm ~]# ls -l /var/run/libvirt total 16 srwx------ 1 root root 0 Mar 12 08:37 libvirt-sock srwxrwxrwx 1 root root 0 Mar 12 08:37 libvirt-sock-ro drwxr-xr-x 2 root root 4096 Mar 8 13:05 network drwxr-xr-x 2 root root 4096 Mar 11 16:17 qemu Xen: [root@xen ~]# ls -l /var/run/libvirt total 16 srwx------ 1 root root 0 Feb 5 08:53 libvirt-sock srwxrwxrwx 1 root root 0 Feb 5 08:53 libvirt-sock-ro drwxr-xr-x 2 root root 4096 Jan 21 14:38 network drwxr-xr-x 2 root root 4096 Oct 20 18:50 qemu Kernel/hypervisor versions of Xen and KVM servers: kernel-xen-2.6.18-164.9.1.el5 xen-3.0.3-94.el5_4.2 kvm-83-105.el5_4.27 kvm-qemu-img-83-105.el5_4.27 kernel-2.6.18-164.11.1.el5 To troubleshoot, I've been running python interactively as the non-root user.

[libvirt-users] Problems with a logical pool creation
by Rubén Vejabalbán 12 Mar '10

12 Mar '10

Hi all, I am new in virtualization so forgive me any evidence. After pool definition, when I try to create a logical pool I obtain the following error: # virsh pool-define vms.pool.xml > Pool vms.pool defined from vms.pool.xml > > # virsh pool-start vms.pool > error: Failed to start pool vms.pool > error: internal error '/sbin/vgchange -ay vms.pool' exited with non-zero > status 5 and signal 0: Volume group "vms.pool" not found > Is anything wrong with my xml file? <pool type="logical"> > <name>vms.pool</name> > <source> > <device path="/dev/sda2"/> > </source> > <target> > <path>/var/lib/virt/images</path> > </target> > </pool> > Are pools created in this way permanent? Thank you! Jenaro Percal
