Hi list

I´m really new to Xen. My question is probably an easy one. First, yes
i went through the documentation and also came across some messages
that helped me clarify (not so clear actually) my next few question.
They are:

What exactly is a "modified guest". I know linux and BSD´s fall in
this category. But, well i can run an unmodified version of linux,
paravirtualized, with Xen don´t?

Talking about windows, i know i nedd Intel-VT or AMD-V to use it. Will
Windows run paravirtualized or full virtualized in this environmet? I
think "full virtualized" is the answer, but if anyone could go a
little bit further on that...thanks!!

What is involved in "modify" a guest OS?

and last but not least. I came across a number of definitions for
"paravirtualized" or paravirtualization. I know it provides an API for
the virtual machines to interface with rather a full abstraction of
the underlying hardware. I guess that´s not all about it. Once more,
if someone could go furthur with an explanation.

I would like to excuse for these sort of basic question and also wish
to thank for any answar i might get.
