[one-users] Migrated VMs cannot be shutdown

[Javier Fontan]

Can you check that the migrated machines are really running? In some
configurations VMs freeze after migration so when the shutdown message
is sent to the VM it does nothing. If that is the case the problem
could be hypervisor related or something that goes wrong with the
kernel running in the VM. Also give a minute or so after the migration
is done, maybe the shutdown command was sent before the VM could catch
it.
