paravirtualization = exokernel?

paravirtualization = exokernel?

[Geraldo Netto]

Hi all,

Firstly, I would like to thank you all making this great work!

I'm Geraldo a Brazilian 19yo guy that is a xen fan and I'm studying methods
of virtualizations.

Well, I'm new with xen and i would like to know:
does xen works like a exokernel?
how can i contribute to xen project?

That is all guys!

Basically, yes; it exposes a hardware-like interface to domains and relies on 
them to provide their own abstractions.  The primary difference is that it's 
oriented towards running whole OSes, rather than processes.  For instance It 
supports task-switching, protection rings, etc within a domain.

First of all, try to get it installed on a system using the documentation 
provided.  I suggest you start off with the Xen 2.0 branch whilst learning 
but you'll want to get onto -unstable if you start doing development work.

You'll probably find there are gaps in the docs - additions to the documents 
are welcome.  That's not very fun though, so once you've got up and running 
you'll probably want to do some bug fixing or implement some small features.

You'll need to know Python to hack on the tools, and C to hack on everything 
else.

Cheers,
Mark
