Hi Jon, 

your first post says that additional IPs on eth0 in Dom1 are /32 not /22 - 
which is it? 

Also, can you fill in the details on the following:

1. "ip addr show" on Dom0
2. "brctl show" on Dom0
3. "route -n" on Dom0
4. The vif configurations for Dom1 and Dom2 (from their config files)
5. The settings for (network-script ...) and (vif-script ...) in your
   xend configuration file.
6. The version of xen you are running.

Depending on what you come back with, I might have more questions. 

Also, do you have any idea if you would prefer a bridged or a routed
setup?
