Hi For what it is worth, Fedora 16 will enable this functionality again, a long gap after Fedora 8. http://searchservervirtualization.techtarget.com/news/2240036580/Linux-kernel-to-fully-support-Xen-Too-little-too-late "Core to KVMâs rapid success is the fact that itâs included in the kernel. In contrast, Xen has always worked well on Linux platforms, but since 2007 users have needed to apply a significant kernel patch and do some configuration not included in the core Linux distributions to make it work. Thatâs a headache and a support issue for OSS vendors and IT staff. By contrast, since KVMâs inclusion in the kernel and declared support from the major distributions such as Red Hat and Ubuntu, getting a KVM environment going is easier and also encouraged by the distributors." "The Xen community has been trying to get Xen introduced into the Linux kernel for years, but the need for multiple kernel binaries was always a sticking point with Linux kernel maintainers. In 2009, Linux creator Linus Torvalds wrote that "Xen really is horribly badly separated out. It gets way more incestuous with other systems than it should. It's entirely possible that this is very fundamental to both paravirtualization and to hypervisor behavior, but it doesn't matter -- it just means that I can well see that Xen is a f---ing pain to merge."
