Howdy.

KVM's live migration support used to support an exec: protoco, allowing 
  either a completely arbitrary transport or a mechanism for storing 
system state to a separate file for later resurrection, being used in 
the latter by libvirt's qemu driver. I notice that this support no 
longer exists in the current codebase.

Would a patch reimplementing this support be welcome?
