No. I never experienced loss of networking in the Dom0. My guess is that your bridge interface isn't configured correctly. There's a bunch of good documentation on how Xen uses the different network interfaces.  http://wiki.xensource.com/xenwiki/XenNetworking helped me understand it better.

Gary,
I don't have a single DomU yet, as soon as I install Xen and reboot, I lose all network connectivity so I haven't proceeded! Is what you describe applicable to the Dom0 in any way?

Thanks!
