Thanks for the help Pasi.  So why use Debian network scripts in lieu of Xen scripts when the Debian wiki doesn't suggest it? 

I removed 'bridge=eth0' from the network-script line but I'm still having trouble with the xen daemon.  When I boot up it isn't running and when I shutdown it still hangs apparently because it's getting no response from eth0.  Do I have to do something to make my change to xend-config.sxp permanent? 

When I try and start up xend I see this error:

# xend start
ifdown: interface eth0 not configured
RTNETLINK answers: Device or resource busy
/etc/xen/scripts/network-bridge: line 240: sigerr: command not found

Sounds like 'eth0' is not a bridge. So probably wrong bridge= parameter used for that vm.

eth0 is my dom0 network interface so the problem is that it is already in use correct?

I'd recommend to disable xen network-script in /etc/xen/xend-config.sxp
and set up the required bridges using debian network scripts.
