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.
