You should be able to use the CD to boot multiple copies of RH9
Linux. If you install the images and tools on your hard disk you
should be able to run any manner of Linux distributions
concurrently,.

That's correct. The aborted NetBSD port is rather old and not
very helpful as a reference. Kip Macy has kindly been putting
thought into a FreeBSD port.
The XP port can only be released to signatories of the Microsoft
Academic Source License, which has very reasonable terms, but is
only available to researchers in other Universities.

There used to be a web-based interface written in tomcat/java,
but I'm afraid it's got out of sync with the underlying tools.
Source is included in the bitkeeper repository
(tools/control/web), so you're very welcome to fix it ;-)

Our goal is to provide this level of isolation. We believe Xen
already provides good security isolation, though there's always
the possibility of bugs. Resource isolation is tougher, but we
believe with our VMM approach we have a _much_ better chance of
achieving this than attempts to host multiple users/applications
from a single operating system image (e.g. vservers).

We currently only support one OS using the graphics console. We
have a plan to support secure display virtualization, but have
yet to implement it. There's been discussions in other threads
about providing high-performance sharing of graphics cards.

I'm afraid there are no plans for a general release the XP port
-- this aspect of Xen is very much a research project.
Best,
