what options do you have in your xend-config.sxp? Do you have bridge-utils
installed?

some network options I use in my xend-config.sxp are:
(network-script network-bridge)
(network-script network-dummy)
(vif-script vif-bridge)

and in my domU configs i have something like this:
vif  = [ 'ip=10.1.2.94' ]

and I also have that same ip in a static config for networking in the
domU.
