RHEL-5.1, Centos 5.1 and Fedora would give you a solution for this out 
of the box through its virbr0 interface created by libvirt by default. 
All that you have to do is edit /etc/xen/xend-config.sxp and specify 
(network-script  /bin/true). That is it. I am not sure about other distros.

IP address shouldn't have any effect in domU, but mac address has always 
worked for me. An example entry from my config file is as below.
vif = [ 'mac=00:16:3e:3b:f7:80, bridge=xenbr1' ]
