No. But you have to tell via config (I don't know how KVM does this) which
bridge the VM is going to use. And if you want it to be reachable via two
bridges you have to set it up for two bridges and give it two IP numbers.
And the packet then has to come in thru the correct interface/bridge, there
is no "bridging" between the bridges. You would need to set up some
additional routing to work around this (probably, I'm not a routing
expert).
Is that possibly not the case? e.g. your VMs are still setup to use only
one bridge?

There ended up being 2 things at work against me. 1, stupidity and the other equipment.
There are 5 Ethernet cards installed... eth0 through eth4. I've been using eth2 successfully. When I removed all ifcfg-X scripts and recreated them, the actual ethX devices were added in the opposite order. My eth2 still worked because it was in the middle, but the other 4 had swapped. I never noticed since eth2 was still working... id10t (me that is).
The other issue is that any of the bridged network cards would not communicate with my router. I had to put a switch between them and the router, nothing else. I saw this by accident in that I could only get 1 ethX device to work at a time, and it ended up following the cable attached to a switch, not router. Other routers work... but this one running DD-WRT doesn't, unless there is a switch between it and the bridged device.
So... the config for all but br2 ended up being what I had originally, but no IPs assigned at all. I've also enabled STP and haven't bothered to see if this actually does anything.
So my brX scripts are like this:
DEVICE=br0
TYPE=Bridge
BOOTPROTO=none
>DELAY=0
STP=on
The only device that has a static IP is br2, all others are set to none, but each VM works. Even the Untangle setup where it bridges the two assigned VM nics works.
Thanks for all the info and help. Sorry it ended up being stupidity and off hardware (strange that Xen Server worked fine though).
Now to somehow get this indexed off of google as searching for a solution brought me to my silly post :)
Thanks again!
