A -xenU kernel can be a bit smaller, but I really don't think there's much 
need to build them nowadays (unless you're building them a lot for testing 
purposes and therefore want to speed up the build process).

If the OP is trying to setup a domU though, the most straightforward way of 
doing so is probably to follows Dan's advince and ferret out the install 
kernel / initrd from the install media, then boot those.  And then it's 
possible to boot the guest using pygrub, which is more like having a native 
system available.  This only works if your host system is using PAE (it 
already is if it's CentOS / RHEL) because that's what the RH Xen kernels 
require.

Of course, if your host is already CentOS / RHEL5 you could probably use 
virt-install / virt-manager to install a domU, and this'll be taken care of 
for you...

Cheers,
Mark
