Things are not quite that simple. The RHEL-5 userspace tools are mostly on a 3.0.3 base, while the hypervisor and kernel are on a 3.1.0 base. The base versions are typically not upgraded during the lifetime of a major RHEL release series. That said, we do have a large number of carefully backported features & patches from newer versions, eg to add support for NPT/EPT, improved HVM support, hugepage support, and much more besides. So just comparing version numbers won't give you a true picture of Xen features available in RHEL-5.
