That's the wrong way around and should be avoided.  It would be bad if
guests started running with drivers that don't implement the same
specification as QEMU.

Therefore the virtio spec should be merged first.  Maybe the Linux
driver can be merged under staging or marked experimental, but it should
not be considered stable before the spec has been accepted by the VIRTIO
Technical Committee.
