[one-users] Migration Problem

[Ruben S. Montero]

As suggested by Oliver in this case is better to save disk.0 and
re-register it again. You could boot it at kvm2 with virsh deploy
deployment.0 but this is only recommended if OpenNebula expects the VM to
be in kvm2, if not it is better to recover kvm1 and recover (virsh deploy)
it there.

Cheers
