While I can't officially speak for Red Hat and exactly what route we may or
may not take in the future, I'd say its a pretty sure thing Red Hat would not
want to maintain two modified linux versions, particularly on an architecture
that makes up such a small percentage of the user base. At the same time, Red
Hat aims to maintain upgrade paths from one version of Red Hat Enterprise
Linux to another, so whatever lands in RHEL6, there will still have to be a
way to run fully virtualized and para-virtualized guests.
Again, not speaking in any official capacity, but note that the default
"Virtualization" software in Fedora right now is kvm, and Red Hat now employs
Gerd Hoffman (aka kraxel), who has been busy working on a project called xenner.
Summary from the README:
xenner is a utility which is able to boot xen paravirtualized kernels,
without the xen hypervisor, using kvm instead.
