This is great because it will mean distributions/admins can integrate Xen faster and with less steps and pitfalls. I've been professionally tied up with Xen for about five years and while I don't have any problems dealing with it, it is still a pain for many people to get started. And much more than just "a pain" if their nodes are using technologies sensitive to kernel changes (which is often the case in HPC).
