Ok, so lets assume you want to use the "desktop" on the Linux distro:
Add a piece of script to the .bashrc:
if -z $VM_STARTED ; then
xm create some-vm-config;
if -n $VM_STARTED ; then
vm shutdown some-vm-name;
export -n VM_STARTED;
This is perhaps not perfect, but it gets something similar to what you
What I'm really trying to say is that there's ways to create a VM based
on some script that is being run at some point - depending on what you
want to do, you may find that the above is OK for you, or not.

Yeah, and that's a problem to XEN in which way? A whole lot of people
aren't using the latest, very newest, graphics card anyways. And many
graphics cards DO work with older drivers, but perhaps at a lower

Give me one example of a "normal" user that needs two OS's on the same
machine simultaneously (as I see it, partitioning the disk is MUCH
easier to manage, but it depends on what you want to do).

And logging in and typing "xm create somename" is very complicated, in
your opinion? Are we talking about auntie Mable, or someone who actually
knows a bit about using a computer? Why would my mum want to run Windows
as a VM in a Linux box? [Although I think if I wrote down "xm create
somename" on a piece of paper, I would only get a call from my mum when
she'd lost the piece of paper...].

Userfriendly to whom?

XenExpress is not distributed "in a distribution", it's distributed by
XenSource, and comes in a package to be installed on your existing
distribution of Linux.
