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.

Hi, I know that FC5 comes with Xen already, and I know that I could have easily used yum to install it. The problem is, that using either of those options I was completely unable to get NAT networking to work, which in my specific case, was a must-have. So, I decided to torture myself, and came up with this process (which really isn't that big of a deal, the most torture is the actual setup of the domU, the Xen and dom0 setup was pretty painless). When installing via source, all I had to do was make sure that the modules needed to run NAT were included in the kernel, and the NAT networking worked perfectly first try. Thus, why I kept my walkthrough, and why I have given it as a resource to those who have had the same problems. Hopefully it will help someone who had the same difficulties as I had.

FC5 comes with Xen already included, and # yum install xen would have installed it for you. FC5 updates currently carries xen-3.0.2 versions for both xen and kernel-xen*. Xen-3.0.2 won't run the early, pre-3.0.0 version of Xen that FC4 used, so to run FC4 on a FC5 host you will need some helping hands; as you described, qemu is ideal for that. Cheers, Stephen
