[one-users] Live migrate failed

[Javier Fontan]

The problem is that for libvirt the default transport protocol is tls
so using plain qemu url (qemu://<host>/system) will use tls. To not
use it the transport protocol should be specified, the easiest one is
ssh as you should have passwordles ssh between nodes.
