Can you ping the domU from the outside world?

Are you using the xm toolstack still (e.g. xm create /etc/xen/test2.cfg)?

If you are using the XL toolstack then you should look at /etc/xen/xl.conf and 
uncomment the bridge line there.

Also if using XL then you need to disable the init.d script for xend and enable 
init.d script for xencommons.

If you're not using the XL toolstack, have you tried that?
