I don't see any sense to use live migration to get up and running a system that fails on an other node!

If heartbeat does not response anymore I assume that either the dom0 with all domUs crashed, so a migration of any domU is not possible at all, or the specific domU is dead and you will get a dead domU on the new system after migration too (I don't know if you can migrate a dead system)!

So if the "source" system does not answer anymore, the only way to get it up and running is to start it again on the same or on a different node.

Live migration is only good for load balancing and planned maintanance issues, not for high availability!
