This depends on: http://lists.gnu.org/archive/html/qemu-devel/2012-09/msg01400.html As far as I know it is #4. It depends on (1) and (2) and (3).

[PATCH v5 00/17] Allow changing of Hypervisor CPUIDs.
Also known as Paravirtualization CPUIDs. This is primarily done so that the guest will think it is running under vmware when hypervisor-vendor=vmware is specified as a property of a cpu.
