[Stefan Ivanov]

Hello all.

I have problem with migration of virtual machines. When i try to migrate 
from hos to host i get this error:
     VMM][I]: Command execution fail: /var/tmp/one/vmm/kvm/restore 
/var/lib/one//datastores/0/4/checkpoint gamma 4 gamma
Tue Apr 16 17:46:30 2013 [VMM][E]: restore: Command "virsh --connect 
qemu:///system restore /var/lib/one//datastores/0/4/checkpoint" failed: 
error: Failed to restore domain from /var/lib/one//datastores/0/4/checkpoint
