We were running on a Ubuntu 8.04 dom0, but I don't think the dom0 should
matter. The HVM guest that we ran was also Ubuntu 8.04, but again I don't
think the domU should matter either.

We ran on pretty nice boxes - Intel Core 2 duos, with 4 GB of RAM. We
gave 1 GB or so to the guest, but you should be able to get away with less.

Another potential use can be for Xen testing and development (since you don't
need a whole physical system to test Xen)

Hope that helps.

Best regards,

Todd Deshane
