I don't think we're ever likely to see the current port available
on 'general release'.

It may (or may not) be possible to re-implement the XP port as
just a new HAL, exploiting Xen's shadow pagetable support. It's
something to look in to...

vmmon assumes its running in ring 0 on the bare metal. There's no
chance of VMware running under Xen (as opposed to the other way
round). Our aim with XenLinux was to implement the full user
space binary API. vmmon would require a very complete x86
virtualization to work.  [Incidentally, does VMware even work
recursively?]
