Mmm?  I may not be the biggest fan of the Red Hat docs but I have to
give a good score to that one about bridged networking.  I followed
the instructions in there and had no problem setting it up on my KVM
hosts.

It has couple of points the OP may need to know. One is that
NetworkManager needs to be disabled. The other is how to handle
iptables (OP disable it while troubleshooting).
