By my experience on cactus release, didnt get a chance to take a look at
diablo milestone 1 features,  the only chance you have to recover a VM after
a server failure, after the VMs sets themselves in "Shutdown mode" , and the
server came back, you can recover them by issuing "nova reboot $instance-id"
, i tested it and work like charm, but if your server dies ... well, you
have to relaunch more instances to replace the dead ones. Of course, doesnt
sound like "ha" but, in cloud ready application environments, you dont
really need to recover dead VMs.

Of course you can take rid of KVM capabilities and integrate it to Virtual
Domain http://www.linux-ha.org/wiki/VirtualDomain_(resource_agent) cool
thing in a nova multinode environment
