Comment 4 for bug 1859210

Also, could you please detail how is the virsh networking (and the broam bridge and its interfaces) set up ?

I tried to reproduce the setup with a container with an extra interface, added that to the "broam" bridge and copied the virsh network definition.
Enabled dhcp in maas for that subnet. I can compose the VM but commissioning times out so I guess there's something wrong in my network setup.
