Yeah.  but again it synchronizes to a backup node (and again you need 
a special/patched hypervisor if you are running 3.3.)

the idea is that the ram state of the vm on the active node and the backup
node are kept synchronized, so when the active node dies, you can activate
the backup node.

My point is that this is different from 'live migration' because you are
using twice the resources.    You are running the live and the backup nodes
in parallel.
