[KVM ] Always freezed, cannot be restored or shutdowned

[ltor]

Hello,
I used 20 open VZ containers without any trouble and three KVM (windows)...
Yesterday, I needed to migrate KVMs (from a hard node to another) them so I did it by stopping them first (not shutdown) and then migrate and restart...but they freezed, could not be accessed, impossible to shutdown via qm command etc...
So I decided to restore them from a backup and always the same situation, qm shutdown impossible (only stop ans start) and I cannot connect to them (rdp) or VNC.
Here is the log of the backup :

May 08 05:13:54 INFO: Starting Backup of VM 121 (qemu)

And the log of th restore operation :

Any idea (eveything update) ?

Sorry !
I answer to my self, the trouble is quite different, KVM can be started on one node...not the other.
The difference is that I migrate to make a distribution upgrade of one the hard node and since this time, only Openvz works fine...another trouble on this upgrade node is that nfs backup cannot be achieved because it tried to mount twice the volume...strange...to follow...
