Yes, we continue to require full re-connection if the save/restore or
migration is successful and the guest is resumed in a new domain context.
There's no question about that. Our aim here is to allow a save/restore or
migration to fail gracfully by resuming execution in the original domain
context. Currently that is simply not possible, but it's not hard to fix.
