You can automagically create the virtio devices on the virtio bus, 
passing through any properties.  usb-storage does this for example with 
the scsi-disk device it needs.  But then you can't have a generic 
virtio-pci device any more.  You need a virtio-blk-pci which creates a 
virtio-bus and virtio-blk.  So it doesn't buy us much over the current 
situation ...
