So long as it has the stuff that's needed (python, python devel package, 
python-twisted, iproute2, bridge utils, curl devel package, zlib devel 
package, etc.), and you can install and boot from a Xen-ified domain 0 
kernel, yes. I never used UL, so I don't know if it has all the things 
that are required.

It's not a "program" per se, in that it doesn't run on top of Linux; Xen 
itself is a "hypervisor", or a supervisor for supervisors, that lets you 
partition a machine into several virtual machines and run 
specially-modified Linux kernels (or NetBSD, or FreeBSD, or Plan9) in 
each. The programs that run in domain 0 just control the Xen 
hyperkernel, telling it what to do.
