How to remove virbr0

[Kevin Wilson]

Hi,
I recently installed Fedora 20 on x86_64 machine . I
also installed several packages on this machine. When I boot my Fedora
20 machine, "ifconfig -a"  shows that there is virbr0 and it is up.
It is probably due to some rpm/service which I installed.
Any idea which rpm/service could it be ? is there a way I could find
(apart from guessing) which
rpm/service is that one ?

Regards,
Kevin
