I'm still a beginner in the world of Xen, but I did dive in pretty hard right away and learned a few good tricks. This page is a page of notes I took for myself for setting up exactly what you're trying to setup, a FC4 domU on a FC5 dom0. http://mitopia.net/index.php/Xen_3.0.2_Setup Mine too was necessary to for my mailserver (Scalix) to work, and it works perfectly in this environment. I am still tweaking with the IP-Tables portion of the NAT networking, but it is working. Hope this can be of some help.

I get through the install questions and then am told that my url is invalid. I thought it was my tree so I made another ... then tested that with a FC4 install on a separate box and it works fine. I don't see any hints in the logs and if I switch to my FC5 tree the install takes off with out a problem. Can anyone point me to a tutorial or some reference for this.... I have googled around quite a bit and not found anything at this time...... Thanks all help is appreciated. E./ -- Fedora-xen@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-xen
