Just curious. You DO use RHEL4's kernel-xenU package, and not
CentOS/RHEL 5's kernel-xen for your domU, right? I believe kernel-xen
for RHEL4 is available starting from RHEL 4.5.

No, sorry. Havent' had the need to create one.

says the steps (an therefore config) is the same as installing RHEL5

That's odd. It should work. I'll try it out later.
On another note, if you use Xen 3.1, you should be able to use dom0
x86_64 and domU i386 kernel, PV guest. I believe this is a better
approach since PV guests gives better performance compared to HVM.

Why would i686 be a problem?
