I've just gone through similar situations and now have everything
working like I want. One of many problems I had was the one above
(and I'm not sure which thing I did fixed it.)
So here's some ideas:
1. Make sure you aren't using NetworkManager. It seems to do unexpected
things automatically, and according to
http://wiki.libvirt.org/page/Networking#Fedora.2FRHEL_Bridging
is doesn't support bridging as of F9. The instructions at that URL
pretty much gave me everything I needed to get things going.
2. When I set my interface as you have (mac address and soruce bridge only)
it adds a target dev=vnet0 automatically. And this works.
3. You might need to update some packages. On the client I was unable
to make NIS work until I updated the ypbind package.
Good luck.
