I use KVM(Libvirt) Debian guest on Leap 42.3.
For guest backup data, attach /dev/sdb(sata HDD) do not work.
# lsblk
...
...
sdb      8:16   0  2.7T  0 disk 
������sdb1   8:17   0   80G  0 part
������sdb2   8:18   0  400G  0 part 
������sdb3   8:19   0   80G  0 part 

command: 
# /usr/bin/virsh attach-disk [guest domain] /dev/sdb vdb --live --type disk
error: Failed to attach disk
error: internal error: unable to execute QEMU command 'device_add': Unsupported
bus. Bus doesn't have property 'acpi-pcihp-bsel' set

On Leap 42.2, this command worked well, no problem.
