While Xen will probably return in RHEL 7 simply because it is part of the
upstream kernel now I doubt it will be officially supported by Red Hat.
Between buying Qumranet (http://www.redhat.com/promo/qumranet/) and now
Gluster (https://www.redhat.com/promo/storage/) it is clear that Red Hat
aims to become a provider of a complete independent virtualization stack
and is unlikely to support "competing" products directly.

The question is what does Xen offer that KVM cannot provide? Looking at the
slides of the KVM Forum 2011 (http://www.linux-kvm.org/page/KVM_Forum_2011)
there seem to be many interesting improvements in the pipeline so at some
point the question really is why hold on to Xen at all when there is not
real reason to?
