That'll be fun to debug later ;)

I think from memory the problem with EL5 was that you had to run the
kernel-xen package - as it wasn't included in the stock kernel. It'd
also be easier to do a netinstall vs a CD install and supply it the
vmlinuz / initrd of the xen installer.

Either way, Xen 3 has been end of life for many years now - so as far as
security go, I wouldn't be putting them anywhere that could be abused.
