    This doesn't improve virtio-net in any way.

    virtio already supports this model; see lguest and s390. Transporting
    virtio over vbus and vbus over something else doesn't gain anything over
    directly transporting virtio over that something else.

    I have a truly marvellous patch that fixes the bug which this
    signature is too narrow to contain.
