Yes, NM will show vibr0 interfaces anyway, but the commands, which I posted, should help you in case, when NM disconnects your virbr0 interface and then it keeps connecting it.

When virbr0 was in "connecting" state, I was not able to reach my virtual machines until reboot. But then, I found net-destroy and net-start commands and after their execution, I don't need to reboot to fix network connection to my VMs.
