I'm not too familiar with that code either, though I have a basic
understanding of what it is doing of course. I wonder though whether
you could give us a bit of a clue as to where you are trying to go.
From the messages you have send I presume you are most interested in
the Windows guest code, and you don't really need a detailed
understanding of the core virtualisation code for that - understanding
the concepts around it would be more important in that case - but it
would still take you a lot of time to work through it which you might
prefer to spend on the code which really interests you. I can still ask
one of our core virtualisation team members to give you a pointer of
course in case I am wrong there.
