Hi all,
I've been doing some experimenting with Xen and have been happy with
the results for my first domU (called gutsy); so much so I have
decided to use Xen on my 4X core Xeon system. Unfortunately, I can't
seem to get networking on any other domU (called mailtest). ANy help
you could provide would be greatly appreciated!
Here is my relevant info:
