Maybe you'll find something useful in these detailed instructions for
nmcli [1][2] or nmtui [3].
I see that [3] says: "Note that a bridge cannot be established
over Wi-Fi networks operating in Ad-Hoc or Infrastructure modes."
... not sure exactly what that means or if it affects your situation.
Lots of moving parts here: distro packaging differences, multiple
network management schemes, libvirt changes. My network
competence is very low, I hope I'm not adding too much noise
to the thread, I'm just here hoping to learn from how you solve it.
