The "short" version would feature "download, build, install and
configure Xen" I'm afraid :-/ I'd be more than happy to help you do that
if you want though and if you can keep a suitably configured system
around (it needn't be dedicated to Xen other than when testing Xen
specifically) you won't need to do the majority of the setup again.
