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

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
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 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.
Ubuntu Hardy Information
If kernel is patched, compiled and installed from source as described in Installation on Linux 2.6, and also in Dapper section above, this alternative method can be used to create an initrd image after modules are successfully installed (assuming the kernel source is 2.6.22.19 and vserver patch is 2.2.0.7):
update-initramfs -k 2.6.22.19-vs2.2.0.7 -c
Look up man 8 update-initramfs for details.
