Hi list,

I cannot start any VM after reboot my hosts on oVirt 3.5.2 and 3.5.2 nodes. It failed on nodes with this error :

hread-11544::ERROR::2015-05-27 19:17:42,479::vm::2331::vm.Vm:: (_startUnderlyingVm) vmId=`4e349319-72e1-42ee-a74c-3dbd8ca45e4b`::The vm start process failed Traceback (most recent call last): File "/usr/share/vdsm/virt/vm.py", line 2271, in _startUnderlyingVm File "/usr/share/vdsm/virt/vm.py", line 3335, in _run File "/usr/lib/python2.6/site-packages/vdsm/libvirtconnection.py", line 111, in wrapper File "/usr/lib64/python2.6/site-packages/libvirt.py", line 2709, in createXML libvirtError: internal error Cannot parse sensitivity level in s0

Hey Kevin,

can you please tell me the exact Node version you are using?

We have actually seen this error before, but we actually assumed that it was fixed a few weeks ago.

Hi Fabian, I use Node version 3.5 - 0.999.201504280933.el6. I cannot use an el7 version now because our nodes are on HP servers and we need the cciss module. --- Kevin

Hi, When I use the Live migration through the oVirt Administration Portal, everything works fine without any errors, but When I want to migrate VMs using the command virsh migrate, it doesn't work at all. The connexion works fine : [root@unc-srv-hyp2 ~]$ virsh -c qemu+ssh://root@unc-srv-hyp1/system Please enter your authentication name: root Please enter your password: Welcome to virsh, the virtualization interactive terminal. Type: 'help' for help with commands 'quit' to quit virsh # hostname unc-srv-hyp1.cfu.local But when I try to live migrate I have the same issue from any of the two hypervisors : [root@unc-srv-hyp1 ~]$ virsh migrate --live unc-cli-xrt qemu+ssh://root@unc-srv-hyp2/system Please enter your authentication name: root Please enter your password: Please enter your authentication name: root Please enter your password: error: Failed to open file '/rhev/data-center/f422de63-8869-41ef-a782-8b0c9ee03c41/d7b9d7cc-f7d6-43c7-ae13-e720951657c9/images/dd4801b5-310c-4bc2-b330- a47ec9bb9870/0d05a0e4-726b-4e6e-b25a-0f85e6c983f3': No such file or directory Have you any ideas to find the answer ?

Hi, Thanks for your answer, in fact I just want to have a rescue command, if I have an ovirt crash. I was thinking that it could be a good solution using virsh on the hypervisors. I don't have a log experience with API/shell, and seems to be heavier to use than command line. Could you give me examples using VdsClient or API/shell for Live migration.

you better not do that

The connexion works fine : [root@unc-srv-hyp2 ~]$ virsh -c qemu+ssh://root@unc-srv-hyp1/system Please enter your authentication name: root Please enter your password: Welcome to virsh, the virtualization interactive terminal.

Type: 'help' for help with commands 'quit' to quit

virsh # hostname unc-srv-hyp1.cfu.local

But when I try to live migrate I have the same issue from any of the two hypervisors :

[root@unc-srv-hyp1 ~]$ virsh migrate --live unc-cli-xrt qemu+ssh://root@unc-srv-hyp2/system Please enter your authentication name: root Please enter your password: Please enter your authentication name: root Please enter your password: error: Failed to open file '/rhev/data-center/f422de63-8869-41ef-a782-8b0c9ee03c41/d7b9d7cc-f7d6- 43c7-ae13-e720951657c9/images/dd4801b5-310c-4bc2-b330- a47ec9bb9870/0d05a0e4-726b-4e6e-b25a-0f85e6c983f3': No such file or directory

Have you any ideas to find the answer ?

you're missing the administrative tasks ovirt does on top of base libvirt. If you absolutely need/want to use a cmdline tool there is vdsClient. It's also still unsupported but it's a bit better… What problem are you trying to solve? Normally you should use API/shell for scripting, etc. Thanks, michal
