Hi, Is libvirt supported on Citrix Xenserver. I have been searching for the same with little/no luck. If supported, can you point to some links/documents which can help me try out the same. Thanks, Naresh

[libvirt-users] problem w/ libvirt-0.8.2-15.el5 and CentOS
by Jim Glennon 20 Jul '11

20 Jul '11

I am running the Eucalyptus 2.0 cloud computing platform on an up-to-date CentOS 5 using the xen hypervisor. While attempting to attach a volume successfully created using jclouds with eucalyptus to a running VM instance, I encountered the following error: libvirt: Requested operation is not valid: Xm driver only supports modifying persistent config (code=55) i also tried attaching manually (i.e. euca-atttach-volume) and experienced the same failure. i found this discussion which mentions a possible libvirt/xen problem: https://bugzilla.redhat.com/show_bug.cgi?format=multiple&id=662908 however it does not appear that the fix is available for public consumption (at least i couldn't find it). from the Eucalyptus nc.log: [Tue Jul 19 22:16:47 2011][005714][EUCAINFO ] doAttachVolume() invoked (id=i-4DA80924 vol=vol-59CF0630 remote=/dev/etherd/e0.12 local=/dev/sda2) [Tue Jul 19 22:16:48 2011][005714][EUCAERROR ] libvirt: Requested operation is not valid: Xm driver only supports modifying persistent config (code=55) [Tue Jul 19 22:16:48 2011][005714][EUCAERROR ] AttachVolume() failed (err=-1) XML= [Tue Jul 19 22:16:48 2011][005714][EUCAERROR ] ERROR: doAttachVolume() failed error=1

[libvirt-users] Unable to start libvirtd 0.9.3 on Ubuntu 10.10
by Heath Petersen 13 Jul '11

13 Jul '11

I just built libvirt 0.9.3 on my Ubuntu 10.10 box. It appears to have built correctly. When I try "virsh -c qemu:///session list --all" I get the following: error: Failed to connect socket to '@/home/heath/.libvirt/libvirt-sock': Connection refused error: failed to connect to the hypervisor After that, libvirtd isn't running as user heath as it did when I was using 0.9.2.

[libvirt-users] Problem starting libvirtd 0.9.3 on Ubuntu
by Heath Petersen 13 Jul '11

I just built libvirt 0.9.3 from scratch on my Ubuntu 10.10 system. It appeared to build and install correctly. When running a command like 'virsh -c qemu:///session list --all', I get the following: error: Failed to connect socket to '@/home/heath/.libvirt/libvirt-sock': Connection refused error: failed to connect to the hypervisor When looking into it, I realized libvirtd was not running as user heath after the command. Running it with LIBVIRT_DEBUG=1, I get: ... 22:26:34.334: 8385: debug : remoteOpen:774 : Auto-spawn user daemon instance 22:26:34.334: 8385: debug : doRemoteOpen:487 : proceeding with name = qemu:///session 22:26:34.334: 8385: debug : doRemoteOpen:497 : Connecting with transport 1 22:26:34.378: 8385: debug : doRemoteOpen:544 : Proceeding with sockname @/home/heath/.libvirt/libvirt-sock 22:26:34.378: 8385: debug : virCommandRunAsync:1874 : About to run LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games HOME=/home/heath USER=heath LOGNAME=heath /usr/local/sbin/libvirtd --timeout=30 22:26:34.378: 8385: debug : virCommandRunAsync:1890 : Command result 0, with PID 8386 22:26:34.379: 8385: debug : virCommandRun:1711 : Result status 0, stdout: '(null)' stderr: '(null)' 22:26:55.430: 8385: debug : do_open:1059 : driver 7 remote returned ERROR 22:26:55.430: 8385: debug : virUnrefConnect:145 : unref connection 0x8451840 1 22:26:55.430: 8385: debug : virReleaseConnect:94 : release connection 0x8451840 error: Failed to connect socket to '@/home/heath/.libvirt/libvirt-sock': Connection refused error: failed to connect to the hypervisor I then tried to start libvirtd manually with 'LIBVIRT_DEBUG=1 LC_ALL=C PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games HOME=/home/heath USER=heath LOGNAME=heath /usr/local/sbin/libvirtd --timeout=30', just like it appears virsh is trying to do.

[libvirt-users] virt-manager/libvirt backwards compatibility problem?
by Whit Blauvelt 12 Jul '11

12 Jul '11

Hi, Wanting to test some recent features of libvirt, I installed 0.9.3 on a couple of systems. It works fine on those, but since upgrading neither of them can successfully connect with virt-manager or virsh to a couple of other systems running libvirt 0.8.3. Even after upgrading virt-manager and virtinst to the latest versions on the 0.9.3 systems, they fail like this in virt-manager: Unable to open a connection to the libvirt management daemon. Libvirt URI is: qemu+ssh://root@192.168.1.67/system Verify that: - The 'libvirtd' daemon has been started Cannot recv data: : Connection reset by peer Traceback (most recent call last): File "/usr/src/virt-manager-0.8.7/src/virtManager/connection.py", line 1055, in _try_open None], flags) File "/usr/local/lib/python2.7/dist-packages/libvirt.py", line 102, in openAuth if ret is None:raise libvirtError('virConnectOpenAuth() failed') libvirtError: Cannot recv data: : Connection reset by peer Virsh simple fails with: error: Cannot recv data: : Connection reset by peer error: failed to connect to the hypervisor Since it's certain that the libvirtd daemon has been started on the other systems (they have production VMs that are running), this leaves me puzzled. This connection for virt-manager worked flawlessly for months when all the systems had libvirt 0.8.3. Is this a known incompatibility? Something I have to tweak somewhere? Thanks, Whit
