Public bug reported:
libvirt-manager or virsh iface-list -all don't show all interfaces available in
the system.
Specifically, I've 2 bridge defined (br0 and br1) and only br0 shows up in the
selectable menu or in the listing. On 16.04, all bridges show up.
On 18.04 box, ip link gives:

on the same box, virsh iface-list --all gives:

On a practical side, on the 18.04 box, filling in br1 as interface for a
vm definition works (only tested in virt-manager).
