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

[王根意]

Hey guys:

I have a running vm with ceph backend:

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


And *snapshot-create-as* works well:

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


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

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


And the vm went paused state.

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



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