What would this do for devices using the virtio-ccw transport?
From libvirt's point of view, the option "disable-legacy=on" would be
added to the device's commandline argument. For the effect, you would
need to ask a qemu virtio person, or even better - a qemu s390 person
who knows something about about virtio. I Cc'ed Michael (the former) and
Cornelia Huck (the latter, according to this patch I found:
