The other problem with taking patch 3 alone is that it completely
breaks everything, because:
* by default we create a "cdrom" drive whose type is <board-default>
and which has no media inserted
* the virtio-blk device barfs if you give it a drive with no media:
"Device needs media, but drive is empty"
The S390 systems get around this by specifying no_cdrom = 1, but
it doesn't seem terribly satisfactory that this has to be manually
done by any machine with a virtio default drive type...
