There are two bridges, IIRC, virtbr0 for a local network (which is what 
you're using) and eth0.  Previously the you would have had something 
like virbr0 and xenbr0 where xenbr0 has dom0's eth0 and peth0 on it; in 
Fedora8 eth0 is the bridge instead.  You probably want to use that 
instead of virbr0.
Now that the bridge has an IP address you can, again IIRC, do cool 
things with iptables for traffic flowing through the bridge without 
having to use ebtables.
