I was interested in running Fedora Core 12 amd64 as dom0. Since the default kernel has no dom0 support, I wanted to use the myoung dom0 kernels. Unfortunately, they won't work with Xen 3.4.2 which is the latest included build in Fedora Core 12 and even Rawhide. I took the latest 3.4.3 build, rolled them into RPMs, and installed it. This works with the myoung kernels. Hopefully it will be of use to some of you. If there is interest, I'll stand up a yum repo for this. Chime in with a comment if you are in need of this.
I'm quite interested in the Eucalyptus Cloud platform. I wanted to run it on a Fedora Core 12 amd64 platform, yet they only make RPMs available for CentOS. I corrected a bunch of things in the spec files and rolled binary RPMs for Fedora. I hope they are useful. If there is demand I'll stand up a yum repo for them as well. Please chime in with comments if you are interested in this.
