I got it working. It was an issue with eth0 being moving out of the way and bonding was not truly working. I added a custom network-bridge script and attached my DomU to a new bridge and every thing is now working.  Thanks for the help.

Xen renames eth0 to peth0 and creates a bridge named eth0. Are you sure that your bond is working after xend starts up? Generally you have to rename the actual physical device eth0 or use custom network-scripts to keep this from happ
