Thanks for the reply. Unfortunately I still can't seem to make it work.
I've switched my guests to use eth2 instead of virbr0, but now they
can't seem to get any connectivity.  I assumed this is what you were
saying to do correct?.  With a guest booted, here is what brctl shows.

bridge name     bridge id               STP enabled     interfaces
eth2            8000.00022d8b1e44       no              peth2
                                                        tap0
                                                        vif2.0
virbr0          8000.000000000000       yes

That looks pretty much the same as the other systems I've used, but it
still doesn't seem to work.

Is it possible that I *have* to write iptables rules to get traffic to
flow through?

BTW, eth2 is my default network device, all others are disabled.

Any help is appreciated.
