Both can be accessed using virtio-blk-s390. The former have the same
semantics on geometry as what we're used to. They use normal MBRs and
essentially the geometry doesn't mean too much these days anymore ;).
However, if possible, I would like to diverge these as little as
possible from x86 virtio disks.
If anything, the geometry should be guessed like we do on x86.
For DASD disks, the geometry is important, as its disk label is usually
not MBR, but something s390 specific.
Can we use this to guess the geometry like we do on x86?
Yes, but what do you do with a blank disk? :)
