    SCSI block devices, LUN are not supported; the type was added to avoid possible bug in
case we decide to support this storage/device type in future. See https://libvirt.org/formatdomain.html#elementsDisks
for details.

> Certain appliances/software fail on KVM as they require disk serials (inside of the VM).
The fix would be to add a disk serial (from volume uuid) in the generated libvirt xml for
all disks except for lun/scsi block type disks (which we don't support yet, so we can add
in a deviceType for now and leave some comment).
