It's based on Xen 3.0.3. Amongst other things this means that its HVM support
is not quite so advanced (the specific thing that comes to mind is SMP HVM
guest support is not quite there, but I'm sure there are other fixes to HVM
and other code too in 3.0.4).
I believe the RHEL 5.1 update is slated to include a newer Xen, possibly 3.1.

I'm running my test machines with CentOS 4 and a xen-unstable compiled from
source. Obviously you wouldn'twant to do that for production machines, but
it works well for me.
RHEL5 has the advantage of being nicely integrated into the system. There's
SELinux support for Xen (if you organise your VMs the way it expects, that
is!), there's the nice virt-manager GUI, etc.
You could always try this out using CentOS 5.

ON a 64-bit Xen you can run 64-bit, 32-bit/PAE and 32-bit nonPAE guests under
HVM mode. On Xen 3.1 you can also run both 64-bit and 32-bit/PAE guests in
PV mode.
