[libvirt-users] VM with ceph backend snapshot-revert error

Tuesday, 24 September 2013

Hey guys:

I have a running vm with ceph backend:

root@apc20-005:~# virsh list
...
  Id Name                 State
 ----------------------------------
  56 one-240              running 

And *snapshot-create-as* works well:

root@apc20-005:~# virsh snapshot-create-as one-240
...
 Domain snapshot 1380009353 created 

But when exec *snapshot-revert*, error occurs:

root@apc20-005:~# virsh snapshot-revert one-240 1380009353
...
 *error: operation failed: Error -22 while loading VM state* 

And the vm went paused state.

root@apc20-005:~# virsh list
...
  Id Name                 State
 ----------------------------------
  56 one-240              paused 

When I use qcow2 image backend, Everything is ok! Any idea?
