The engine will try to keep the VM running. So if one host goes down, it will restart the VM on some other host automatically. We will also migrate the VM (or some other to free resources) when the current host gets too loaded. We do not require any migration addons, it just works. But of course we have usually more hosts in a cluster to make this possible. I do not really remember what happens when all hosts are restarted (power outage) though as that is quite special case.
