Xen Installation Notes

apt-get install x11proto-core-dev zlib1g-dev patch make libc6-dev locales python-dev bridge-utils iproute mercurial subversion gcc udev libncurses-dev ethtool g++ libssl-dev

dpkg -P hotplug

cd /tmp; svn co https://ptmc.org/svn/thesis/xen0/

scp -C s.ptmc.org:/backup/xen/home/xen/domains/super.img /home/xen/domains/

carefully move xen0 contents to /

cd /usr/src

mkdir xen-unstable.hg

hg init xen-unstable.hg

cd xen-unstable.hg

hg pull http://xenbits.xensource.com/xen-unstable.hg

hg update

use older make version to avoid rebuilding the whole kernel tree each time: http://snapshot.debian.net/archive/2005/12/15/debian/pool/main/m/make/make_3.80+3.81.b4-1_i386.deb then use dselect and set make to “hold”.

build xen and domU and dom0 kernels and install (see below)

Use grub to boot the Xen0 kernel like this:

title          Xen 3.0 / XenLinux 2.6
root           (hd0,1)
kernel         /boot/xen-3.gz dom0_mem=131072 console=vga
module         /boot/vmlinuz-2.6.16-xen root=/dev/hda2 ro devfs=nomount

Check Xen Issues for necessary patches!!

To apply kernel patches: put patches in patches/linux-[version], remove ref-linux-[version] and linux-[version]-xen(U), make linux-2.6-xen(U)-config, build, install

to (re)compile the dom0 kernel (keeps custom config if it exists), run:

make linux-2.6-xen-config
cp ../xen-kernel-config/.config.xen linux-2.6.16.13-xen/.config
make linux-2.6-xen-config
make linux-2.6-xen-build -j5
make linux-2.6-xen-install -j5

to build the cowloop module, run make; make install in /usr/src/cowloop

to (re)compile the domU kernel (keeps custom config if it exists), run:

make linux-2.6-xenU-config
cp ../xen-kernel-config/.config.xenU linux-2.6.16.13-xenU/.config
make linux-2.6-xenU-config
make linux-2.6-xenU-build -j5
make linux-2.6-xenU-install -j5
/home/xen/scripts/inject_xenU-modules.sh

To update to the latest Xen (builds everything but the kernels):

hg pull -u
make clean
rm -rf dist
make dist-xen dist-tools dist-docs -j5
mkdir dist/check
cp tools/check/chk tools/check/check_* dist/check
rm dist/install/etc/xen/xend-config.sxp
./install.sh

and (re-)apply any Xen kernel patches now.

To check out a specific revision: hg co -C 9515

To run the xen daemon:

update-rc.d xend defaults
/etc/init.d/xend start

Check out xen unstable
