resend: quick pointers needed

resend: quick pointers needed

[liqiang zhu]

hi everyone, I am attempting to port l4 (http://os.inf.tu-dresden.de/L4/) to 
Xen, can you please give me quick pointers how to add a guest OS to Xen?

I have been able to compile xen and boot with it. I have been reading the 
code and existing documentations, I appreciate if you can help me getting 
started.

thanks,

-- Larry

You can start here

http://minixonxen.skynet.ie/cgi-bin/trac.cgi

This focused more towards Xen 2.0.7 but I know of no other documentation
which describes porting an OS to Xen.

You can also take a look at the Mini-OS code which is part of the
xen-unstable tree. That will give you an idea about what minimum work
needs to be done to port an OS to Xen 3.0.

Do you aim for a Dom0, a DomU or both?
In any case, you'll have to rewrite things that aren't fully virtualized 
by Xen. This mainly includes memory management and interrupt handling.
For Dom0, you should be able to use the same drivers without 
modification (not sure though, don't have much experience with Dom0) but 
you'll need to write the frontend/backend drivers for virtual devices.
For DomU, you'll have to write drivers for virtual console, virtual disk 
and virtual NIC.

Mathieu

Hi,

guys from L4 are working on their own paravirtualization solution based on L4
and modified compiler/binutils.

As L4 is a micro-kernel, not a kernel, It should be wiser to use this one
instead of Xen.

Laurent
