This deserves clarification...
Red Hat is a business, and made a simple business decision. Maintaining
Xen support would have meant maintaining a very large set of patches.
They made the decision that the effort (and money) needed to maintain
Xen outside of the mainline kernel was not worth it.
KVM was not chosen over Xen so much as KVM was a much less expensive
hypervisor to support. As for it being mature or not; Well, put on your
kevlar pants because that is a matter of opinion.
As a follow-up, Xen dom0 support began getting into the mainline kernel
at 2.6.33 (EL6 is based on 2.6.32). It is very likely that we will see
Xen dom0 support returned in the next major release.
