It depends how you set up your Xen on SL5 initially..
If you installed them with virt-install and they are installed on
a whole device (/dev/xvda, etc.) then it is pretty easy to flip over
to kvm or bring forward to sl6 and beyond.

If you installed them on individual file systems, e.g. /dev/sda1, 
/dev/sda2 and so forth and you do not have a boot sector internal
to your Xen VM image then it is almost impossible to do anything with
it or to update to anything that is newer. I have seen several
online prescriptions of how to do it but none of them worked for me.
