Urgh, I always do my best to pretend that there is no such thing as live migration :) Never seem to work though :( However if there's an agent connection, it could be arranged in a way allowing the host to reconnect to the guest agent. In that way it really shouldn't be a big deal as long as our agent commands aren't too complex. xmlrpc-c is probably fine, but it introduces a layer of complexity which always makes me worried. Cheers, Jes
