Xen is a "virtual machine monitor". It allows you to host other
operating systems, kind of similar to the way you might run many
instances of VMWare on a linux/windows box but with a more
"performant" implementation. Xen doesn't try to emulate too much
hardware and it actually multiplexes the hardware you have.
As such, you can run many different "domains" with Linux, NetBSD or
Plan 9 [once Ron irons out the last few bugs...:)].
I had a Xen installation up until a few minutes ago when I hosed my
machine doing something else :). Basically you use GRUB to boot Xen
and then a special "Xen-linux" as a controlling "domain 0". From
there you can start a xen daemon which lets you create new domains
with configuration files to assign disk partitions or files as
filesystems for other kernels.
It's fairly cool stuff. http://xen.sf.net has some information I
believe. It's also really easy to build Xen2 from source. The
makefile even downloads the kernel and patches it for you IIRC so
getting started is pretty easy.
I'm buying extra disks just to play with it from my local mom'n'pop
computer store up the street [support the little guy!!!].
