Fedora 7  (no Core in the name anymore) is using 3.1.0  for hypervisor
and userspace. The Fedora 7 kernel is temporarily on 3.0.4 until we finish
the kernel rebase to 3.1.0 + 2.6.21

As you say, RHEL is all about stability so upgrading software versions,
particularly if end user facing commands / tools change, is not really
an option.
