Awesome, that fixed it, thanks.

It was already set for ifcfg-p22p1, so I've added it to ifcfg-br0.

Yes, this I had already done. Networking was working; it was just
applications that seem to be dependant upon NetworkManager control.

I just meant I used both "stop" and "disable".

We'll see if it happens again with Xorg next time I restart.
Unbelievable it would seem so reliant upon NM. There are thousands of
/var/spool/abrt directories, all from the same login.

Very helpful, thanks so much. Do you know of a doc that explains the
proper way to set up NM to provide bridging for kvm and virt-manager?

How do I even access the NM network management GUI from within GNOME?
I really hate this new GNOME.

Thanks,
Alex
