"RHEL is Red Hat's flagship platform and the inclusion
of KVM is the first really big shift for Red Hat's new
virtualization roadmap which favors KVM. Red Hat also has - in
private beta - a standalone KVM hypervisor product as well as new
server and desktop virtualization management application.
"While KVM is the big new item in RHEL 5.4, there are also a few
other goodies for users to try out."
