I presume you did this on the dom0? Why?

You should be *bridging* between your physical eth0 and the domUs. 
Consequently, there's no need for the dom0 to know what address the 
domUs are using at all -- if the bridge is up, packets will flow across 
the bridge to the dom0's physical ethernet device without any 
configuration on the dom0 which is in any way specific to the IP in 
question or to Xen.
In short, I think you're making this much harder than it needs to be. 
Look at the network-bridge script which comes with Xen to see what steps 
are generally used to start things up -- and if things don't work, look 
be sure to look into whether your firewall is obstructing the flow.
