What kind of bridging are you using? Standard NAT'ed virbr0 bridges? If 
so, can you/have you tried using traditional bridging? That should turn 
the bridge into more of a traditional switch instead of relying on 
packet routing... I've had no trouble with VM clusters, but I only ever 
tested with both VMs on the same host.

Here's how I build my bridges:

Of course, you could create a stand-alone bridge and use brctl to attach 
the real interface instead of modifying the network config, if you just 
want to test. Once the bridge is built, simple adjust the VM's config to 
use the new bridge. If that works well, then you could consider a more 
permanent config.
