I like the VIRTIO_BLK_F_SCSI flag - it avoids some problems we had with an
earlier version. (I believe we found a solution, but this explicit check
looks much more reliable)
I gave this patch a short test with the kuli loader (s390 userspace). You can
consider the "VIRTIO_BLK_F_SCSI not available" case
