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 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 dietlibc

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