Hi Niels, I haven't followed the most recent developments for the Xen HA resource (so I'm sorry if I missed something), but there is a conceptional issue I have with Heartbeat orchestrating a live migration: what would be the criterium to start such a migration? Typically Heartbeat reacts when either a node or a resource is dead. If a Xen resource is dead it cannot be live migrated anymore (since it is dead), so you would need to predict a disaster from happening in the next couple of seconds/minutes and I don't really see how to do that.
