At this point, followers and users of Red Hat Linux may be asking, “What about Xen?” (the best-known open-source hypervisor technology to date.) Red Hat, according to Red Hat executive VP Paul Cormier, will continue to support both Xen and KVM. But, because “KVM is now baked in to the Linux kernel, it’s very easy for both Red Hat and other developers to work with it,” Cormier says. For the time being, Xen will continue to be important, but, as time goes by, Red Hat sees KVM becoming the dominant virtualization technology, he says.
