This is known not to work.  It fails in my automatic tests.

The current RHEL6 kernel has enough pv-on-hvm drivers to get the
toolstack to try to negotiate with the guest during save, but not
enough (or not working enough) drivers to actually complete the
negotiation.  So the toolstack times out and the migrate/save fails.
