You do not need to compile entire Xen and a dom0 kernel if you are running Debian Lenny...

Just install Debian Lenny and to install Xen, run:

apt-get install xen-linux-system-2.6.26-1-xen-686
reboot

Hi
I was wondering what is the official procedure to compile Xen 3.3.1. In fact the readme that comes with this release says:
make world
make install

however, this does not copy the compiled vmlinuz-2.6.26-1-xen-686   into /boot
it seems that I have to run

./install.sh

as well.

if instead I say:

make world KERNELS="linux-2.6-xen0 linux-2.6.-xenU"

as suggested in the readme and in the users manual, I will get:

vmlinuz-2.6.18.8-xen0 and vmlinuz-2.6.18.8-xenU  ( note the different versions )

also , the xen download site talks about 2.6.18.-8 and not ( yet ) about 2.6.26.1

in a recent mail , the following procedure was suggested:

Hi:
Please refer to http://www.xen.org/download/docs/xen33.linux-2.6.18.README.txt.

steps:
1. download the xen-3.3.1.tar.gz
2. tar -zxf xen-3.3.1.tar.gz
3. Download kernel code by "http://www.xen.org/download/docs/xen33.linux-2.6.18.README.txt"
4. cd to folder xen-3.3.1
5. make prep-kernels.
6. run other make commands you want.( you can get help by "make help")


enjoy your time :)

My questions are:
on a fresh debian lenny system:
1) what is the recommend installation command sequence ?
2) what is the recommend kernel version for dom0 and domU ?

Thanks very much for your help

Hi
Thanks very much for your help.
In fact, I wanted to compile myself to better understand xen and also because I will ultimately want to build a custom kernel with xen.

I also think it could benefit to other users if installation instructions were consolidated in the different places where they appear. For example, the README of the latest 3.3.1 tarball suggest , that you call

make world KERNELS="linux-2.6-xen0 linux-2.6-xenU"

however the Installation instructions on the web reads as follows:

... Many users will be better off using the "-xen" kernel instead of "-xen0" and "-xenU" kernels. ....

In fact, the usage of the make world command is not suggested !

I did the following to successfully install xen 3.3.1 on debian lenny. This is adapted from thoandswelt.blogspot.com/2008/10/xen-33-installation-auf-debian-etch.html  ( in german ) and maybe it would be useful for people new to xen to have something clear and straigthforward on the xen website ( maybe its already there but I missed it ... )

(my) Installation Instructions for xen 3.3.1  on a pristine debian lenny 5.0.0  ( please notify if this is incorrect ) :

aptitude update && aptitude dist-upgrade
aptitude install build-essential mercurial gawk libx11-dev libssl-dev zlib1g-dev gettext ncurses-dev python-dev iproute bridge-utils texinfo pciutils-dev
wget http://bits.xensource.com/oss-xen/release/3.3.1/xen-3.3.1.tar.gz
tar xvzpf xen-3.3.1.tar.gz
cd xen-3.3.1
make world && make dist
./install.sh
aptitude install linux-image-xen-686 add this to /boot/grub/menu.lst

title Debian GNU/Linux, kernel vmlinuz-2.6.26-1-xen-686
root (hd0,0)
kernel /boot/xen-3.3.1.gz
module /boot/vmlinuz-2.6.26-1-xen-686 root=/dev/hda1 ro
module /boot/initrd.img-2.6.26-1-xen-686
