The kernel in SL4 is not suitable for the hypervisor/dom0, you need at 
least SL5 (or some Fedora), or replace the SL4 kernel(and some utilities 
- not realy recommended).

SL4 can then run as a domU, with some caveats (cannot mix 32/64 bit 
doms). Jarek has put together a few recipes at
https://twiki.cern.ch/twiki/bin/view/LinuxSupport/XenHowTo

Of course, recipes for CentOS and Red Hat would equally apply, e.g
