Maybe I'm misunderstanding, but a netmask of 255.255.255.255 is only  
one machine, right.  Are you wanting your guest to be isolated on its  
own subnet and route traffic in between?
The way I have my guests setup is attached to a bridged interface  
that's coming from dom0.  All the traffic gets sent from the guest  
across dom0's bridge and out to the network.

If you want Xen to handle the bridging, you'll need to specify:

(network-script 'network-bridge bridge=eth0')
(vif-script vif-bridge)

Then reboot.  When it comes up again, you should see peth0 and xenbr0  
in your ifconfig output.  Edit your guest to use the xenbr0 and you  
should be good to go.
Please note, that this is for a bridged setup.  If you're trying to do  
routed interfaces, I'm not sure what the setup would be there... but  
would be interested to find out.
hope that helps...
