From libvirt package POV this is fixed in >=Focal (20.04) and the only release left affected is Bionic (18.04, libvirt 4.0).
Fixing it in Bionic is IMHO worth to consider but low prio (if users can influence, they can set an address to 8-16 and it works, only the default-no-address use case is broken).
Never the less, fixing it in Bionic won't help your cases on UCA with 5.0/5.4 - those would have to be done by the UCA team. Therefore I'm adding back a cloud-archive task.
