Is there a plan to get this incorporated into the virtio spec [1]? At the moment, I can't see a working draft that includes the new bit. Having it in the spec would help convince implementors that it's not just a Linux thing. Thanks, Will [1] http://docs.oasis-open.org/virtio/virtio/v1.0/cs04/virtio-v1.0-cs04.html
