Are you asking "is it possible to run Xen without Linux?" or "is it
possible to automatically start a VM on top of Xen+Linux when it
starts?"

The answer to the first question is "No"[1]. The answer to the second
form of the question is definitely "Yes", you can add a startup script
to your Linux distribution and make the VM start automagically when you
boot Linux. 

[1] Xen requires SOME host-OS. It can be other things than Linux - there
have been ports of Xen running with other OS's, but it's almost
necessary that it's a "unix-like" OS, such as Solaris or some
BSD-version.

Exactly what type of drivers are you talking about? What is the problem
you're trying to solve (or are you writing a paper on the subject of
"What is the difference between running Windows on bare-metal and on top
of Xen?". Do you have a case-in-point of a driver that you require for
your system to work, that exists under Windows but doesn't under Xen? Is
this still about your hardware info?

But why would ANY NORMAL person use virtualization at all? Most people
don't use computers in a way where virtualization makes any sense in the
first place - so why would they want virtualization (whether it's easy
to use or not)? The average person uses a computer for:
1. Playing games.
2. Web-browsing and e-mail.
3. Writing documents, spreadsheets, presentations, etc. 

Where does any of this get any "better" by running virtualization? What
problem are you trying to solve?

I'm not saying your statement is wrong, but it's like saying that a
Formula 1 car is difficult to drive, so why would a normal person want
one? Well they don't... 

That's of course not to say that efforts to make Xen more userfriendly
would go amiss - but it's not a "every-mans product". Virtualization is,
as of right now at least, a specialized niche, where people who need it
will do what's necessary to get there. 

Also, I believe the user-interface on for example XenExpress is a lot
nicer than that of the open source version of Xen. It's still free to
download. Have you tried it?
