Networking docs are on the wiki:

   http://wiki.xensource.com/xenwiki/XenNetworking

Quite complicated though!

This doesn't look quite right. You're missing some entries that would
usually appear in a default setup. Can you give me the following
information:

1. Output from "brctl show" on Dom0
2. The entries for:

       (network-script  ???)
       (vif-script  ???)

    in your /etc/xen/xend-config.sxp
3. Entries for 'vif' in your domain configuration files if they don't
   just look like:

       vif = [ '' ]

4. Also, can this machine still ping other machines on your network in
   it's preset state?
5. Are you using a version of xen that came with your distro or did you
   download it yourself? And if 'distro version', then what distro are 
   you running?
