Because no one has ever suggested it before...

Arguably we should just turn off STP on the virbr0 device. Since it is
not connected directly to the public LAN[1] there is no risk of network
loops and thus spanning tree protocol is pointless for virbr0. I wonder
if somewhere along the lines post F8 GA, STP accidentally got toggled 
from offf by default to on by default on virbr0. Please file a BZ about
this problem.
