Once I merge the migration patches, I'll help Avi merge this into KVM.  
The whole point of this exercise is to merge the KVM bits into QEMU but 
in the process, I decided the bits needed to be written :-)

Yes.  The primary reason that hasn't been possible in the past was 
because of how memory was migrated.  The new memory migration protocol 
happens to make it easier to let QEMU and KVM be compatible.  That 
wasn't an accident :-)
