With the switch to '-blockdev', it is necessary to explicitly specify
the device ID for SCSI drives, see also [0]. Otherwise, the device
paths in '/dev/disk/by-id' would be missing. For IDE/SATA, the paths
are still present with '-blockdev' without additional changes and
VirtIO block did not have such paths even before. The relevant
'ide-{cd,hd}' and 'virtio-blk-pci' devices do not seem to have an
option that would be equivalent to the 'scsi-{cd,hd}' 'device_id'
option.
While the change should be backwards-compatible even with '-drive',
guard it with machine version 10.0 just to be sure.
