Re: [Users] VM wont restart after some NFS snapshot restore.
Usman, the only thing that comes to my mind is something related to: http://gerrit.ovirt.org/13529 which means that in some way the restored volumes are either inaccessible (permissions?) or their metadata is corrupted (but it doesn't seem so). There is probably another Traceback in the logs that should give us more information. Could you post somewhere the entire vdsm log?
