kvm never supported live migration with v2.  As I think I mentioned in 
another note, I don't want to burden the VMState refactoring with 
supporting a format that qemu doesn't support upstream.  That said, if 
you want to add back a version of it that makes use of the new 
infrastructure, I would be willing to take that.

In fact, if you're willing to do the cleanup work along with Juan, we 
can avoid removing it.

The per device loading functions will be switching to VMState.
