Did you forget virObjectLock(srv) here?

Hm... I guess we need something slightly different. While we may want
one service to stop accepting new clients, we may want the other one to
still accept new ones. But since this is a big split, and so far a
daemon will have only one server, it can be saved for a follow up patch.
