Excellent writeup! Worked like a charm! I used these instructions for Edgy.

 The only issue I ran into was when I was creating Dom1 as I received this error msg:

Error: Device 0 (vif) could not be reconnected. Hotplug scripts not working.

 I also found that /var/log/xen-hotplug.log had:

trap: 53: ERR: bad trap

The fix is to change the first line in all the scripts in /etc/xen/scripts from /bin/sh to /bin/bash and then I could successfully create multiple DomU's!!!! I found the fix in:

Thanks to all!
