Lemsx1: /* Ubuntu Gutsy Information */

== Check Ubuntu's Wiki ==

There are howtos on Ubuntu's site that describe how to download pre-built, Ubuntu-specific kernels.

http://help.ubuntu.com/community/VServer

More detailed instructions on the u32 kernel can be found on http://wiki.u32.net/Ubuntu-VServer

== Vserver Kernel on Ubuntu Dapper with grsecurity ==

=== Prerequisites ===

* 32 Bit Ubuntu Dapper.
* installed packages:

apt-get install build-essential gcc make g++ libncurses5-dev

=== Howto Devel 2.6.17.14-vs2.0.2.1-grsec2.1.9 ===

==== Get the Kernel ====
* Kernel files + patch from http://linux-vserver.org/
** get linux-2.6.17.14.tar.bz2 und patch-2.6.17.14-vs2.0.2.1-grsec2.1.9.diff
*** http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.17.14.tar.bz2
*** http://people.linux-vserver.org/~harry/patch-2.6.17.14-vs2.0.2.1-grsec2.1.9.diff
cd /usr/src/ && mkdir kernel && cd kernel
wget http://www.kernel.org/pub/linux/kernel/v2.6/linux-2.6.17.14.tar.bz2
wget http://people.linux-vserver.org/~harry/patch-2.6.17.14-vs2.0.2.1-grsec2.1.9.diff
tar xfjv linux-2.6.17.14.tar.bz2
cd linux-2.6.17.14

==== Patch the Kernel ====
cat ../patch-2.6.17.14-vs2.0.2.1-grsec2.1.9.diff | patch -p1
cp /boot/vmlinuz-2.6.15-26-server
make oldconfig
make menuconfig

==== Make the Kernel ====
make # this will take a long time
make install
make modules_install
mkinitramfs -o /boot/initrd.img-2.6.17.14-grsec2.1.9-vs2.0.2.1 2.6.17.14-grsec2.1.9-vs2.0.2.1
vi /boot/grub/menu.lst
The Boot entry should look like this
title Ubuntu, 2.6.17.14-vs2.0.2.1-grsec2.1.9
root (hd0,0)
kernel /boot/vmlinuz-2.6.17.14-grsec2.1.9-vs2.0.2.1 root=/dev/sda1 ro quiet splash
initrd /boot/initrd.img-2.6.17.14-grsec2.1.9-vs2.0.2.1
savedefault
boot

==== Test the Kernel ====

* boot Kernel
* ''uname -r'' should show
2.6.17.14-grsec2.1.9-vs2.0.2.1
* run Testscripts
* http://oldwiki.linux-vserver.org/TestScripts

== Alternate Method ==

This is based on [http://oldwiki.linux-vserver.org/UbuntuVserverHowTo UbuntuVserverHowTo] on the old wiki, updated with new links that work as of December 2006.

This is NOT COMPLETE -- remove this message when you get it to work!

==== Get the Kernel ====
apt-get install linux-source-2.6.17 kernel-package linux-kernel-devel
cd /usr/src
tar xjvf linux-source-2.6.17.tar.bz2

==== Patch the Kernel ====
cd linux-source-2.6.17/
wget http://vserver.13thfloor.at/Experimental/OLD-2.0/patch-2.6.17.13-vs2.0.2.1.diff
patch -p1 < *diff
vi Makefile
fix the EXTRAVERSION to be -vs2.0.2
cp /boot/config-2.6.17-10-generic .config

# take all the defaults
yes '' | make oldconfig

==== Make the Kernel ====
time make # this will take quite a while
make-kpkg --initrd binary

== Problems ==

When you recieve a 'Segmentation fault' error running vserver-utils try useing latest [http://www.fefe.de/dietlibc/ dietlibc]

wget http://www.fefe.de/dietlibc/<insert version here>
tar jxvf dietlibc*
cd dietlibc
more README

Or alternatively, use debian packages. The binaries are staticly linked as far as I known so it doesn't matter.
Feity and up gcc version won't let you compile correctly dietlibc yet.

== Ubuntu Gutsy Information ==
This is a note on creating Ubuntu Gutsy as a guest on an Ubuntu Gutsy host. To create the Ubuntu Gutsy host, follow the combination of the [[Installation on Linux 2.6]] wiki page and the [[Installation on Ubuntu]] wiki page.

To create the guest system, do these commands:
# apt-get install debootstrap
# vserver vserver1 build -m debootstrap --hostname=vserver1.mydomain.com --interface eth0:192.168.1.10/24 -- -d gutsy -m http://ftp.ubuntu.com/ubuntu
# vserver vserver1 start
# vserver vserver1 enter

To get networking work on the guest, try the tips from www.unixshell.com/wiki/index.php/creating_and_using_vserver_virtual_servers.
