Can you point me to a link on that?

my install procedure simply:

wget ..../downloads/xen-3.0.0-src.tgz
tar -xvzf xen-3.0.0-src.tgz
cd xen-unstable
make world
make install
sh ./install.sh

/boot/grub/menu.lst
title   Xen 3.0.0 / XenLinux 2.6.12.6-xen0
root    (hd0,0)
kernel  /xen.gz dom0_mem=128M
module  /vmlinuz-2.6.12.6-xen0 root=/dev/hda6 ro console=tty0

In between your steps

cd xen-unstable
make world

Just before the make world, do this

vi Makefile

Change

KERNELS ?= linux-2.6-xen0 linux-2.6-xenU

to

KERNELS ?= linux-2.6-xen

This will help compile the linux-2.6-xen kernel. The same kernel can be used for dom0 as well as domU.

Alternatively you can follow the README file in the xen distribution

make KERNELS=linux-2.6-xen world
make install

As for more documentation, just search this list for xen kernel and posts by Ian, you should see a lot of posts by him on this matter. There is an entry in wiki also on this, however i can't seem to find it right now. However the above works for me for compiling the xen kernel.

Don't forget to create a initrd (read the README file)
