If you are running a system in production you should probably consider building your own kernel based on the vanilla kernel source as described here: [[Installation_on_Linux_2.6]]


There are howtos on Ubuntu's site that describe how to download pre-built, Ubuntu-specific kernels.
The binary kernel images provided here are neither official ubuntu nor official vserver kernel images.  


  http://help.ubuntu.com/community/VServer
If you have any problems with those kernels please send a mail to the Vserver [http://list.linux-vserver.org/ mailinglist] and please '''do not file any bugs on the ubuntu bugtracker'''.


More detailed instructions on the u32 kernel can be found on http://wiki.u32.net/Ubuntu-VServer
If you are interested in a different kernel config or have prepared a patch for newer kernels, do not hesitate to contact the Vserver [http://list.linux-vserver.org/ mailinglist].


== Vserver Kernel on Ubuntu Dapper with grsecurity ==
== Intrepid ==
Intrepid ships with kernel version 2.6.27. As of now (4.3.2009) there are only experimental patches available for this kernel version.


=== Prerequisites ===
I have adapted version 2.3.0.36.4 of the vserver patch to the Intrepid kernel sources. These images should be considered '''experimental''' but seems to work.


* 32 Bit Ubuntu Dapper.
The util-vserver package from intrepid seems to be broken (see: [https://bugs.launchpad.net/ubuntu/+source/util-vserver/+bug/338390 Ubuntu Bug]), therefore I have rebuild the jaunty version for intrepid. This version ships with unstripped binaries due to another [https://bugs.launchpad.net/ubuntu/+source/dietlibc/+bug/254790 Ubuntu Bug].
* installed packages:


apt-get install build-essential gcc make g++ libncurses5-dev
=== Packages ===
The following packages are available for i386 and amd64:


=== Howto Devel 2.6.17.14-vs2.0.2.1-grsec2.1.9 ===
* linux-headers-2.6.27-11-vserver
* linux-headers-vserver
* linux-image-2.6.27-11-vserver
* linux-image-vserver
* linux-restricted-modules-2.6.27-11-vserver
* linux-vserver
* util-vserver


==== Get the Kernel ====
=== Known Limitations ===
* Kernel files + patch from http://linux-vserver.org/
* linux-image

tar xfjv linux-2.6.17.14.tar.bz2
cd linux-2.6.17.14


==== Patch the Kernel ====
=== Repository ===
cat ../patch-2.6.17.14-vs2.0.2.1-grsec2.1.9.diff | patch -p1
You can add the following key to your apt keyring:
cp /boot/vmlinuz-2.6.15-26-server
make oldconfig
make menuconfig


==== Make the Kernel ====
  <nowiki>wget -O - http://ubuntu-vserver.pingworks.net/ubuntu-vserver.pubkey | sudo apt-key add -</nowiki>
  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 ====
Add the following line to your sources.list:


* boot Kernel
i386:  
* ''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 ==
<nowiki>deb http://ubuntu-vserver.pingworks.net/dists/intrepid/binary-i386 ./</nowiki>


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.
amd64:  


This is NOT COMPLETE -- remove this message when you get it to work!
<nowiki>deb http://ubuntu-vserver.pingworks.net/dists/intrepid/binary-amd64 ./</nowiki>


==== Get the Kernel ====
=== Installation ===
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 ====
aptitude update
  cd linux-source-2.6.17/
  aptitude install linux-image-vserver linux-headers-vserver util-vserver
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
== Hardy ==
yes '' |  make oldconfig
Hardy ships with kernel version 2.6.24 which is not officially supported by Linux-Vserver due to the major changes made in this kernel version.


====  Make the Kernel ====
Nevertheless I have adapted version 2.0.0.5.0.7 of the vserver patch to the Hardy kernel sources. We have run those patched kernels for about a year now without any problems on our desktop systems.
time make    # this will take quite a while
make-kpkg --initrd binary


== Problems ==
=== Packages ===
The following packages are available for i386 and amd64:


When you recieve a 'Segmentation fault' error running vserver-utils try useing latest [http://www.fefe.de/dietlibc/ dietlibc]
* linux-headers-2.6.24-23-vserver
* linux-headers-lum-2.6.24-23-vserver
wget http://www.fefe.de/dietlibc/<insert version here>
* linux-headers-vserver
tar jxvf dietlibc*
* linux-image-2.6.24-23-vserver
cd dietlibc
* linux-image-vserver
more README
* linux-restricted-modules-2.6.24-23-vserver
* linux-restricted-modules-vserver
* linux-ubuntu-modules-2.6.24-23-vserver
* linux-vserver


Or alternatively, use debian packages. The binaries are staticly linked as far as I known so it doesn't matter.
=== Known Limitations ===
Feity and up gcc version won't let you compile correctly dietlibc yet.
* linux-image
** CONFIG_OCFS2_FS has been disabled


* linux-ubuntu-modules
** CONFIG_AUFS, CONFIG_GFS_FS, CONFIG_SQUASHFS, CONFIG_DMRAID45 have been disabled


== Ubuntu Gutsy Information ==
=== Repository ===
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.
You can add the following key to your apt keyring:


To create the guest system, do these commands:
<nowiki>wget -O - http://ubuntu-vserver.pingworks.net/ubuntu-vserver.pubkey | sudo apt-key add -</nowiki>
# 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.
Add the following line to your sources.list:


== Ubuntu Hardy Information ==
i386:  
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.
<nowiki>deb http://ubuntu-vserver.pingworks.net/dists/hardy/binary-i386 ./</nowiki>
 
amd64:
 
<nowiki>deb http://ubuntu-vserver.pingworks.net/dists/hardy/binary-amd64 ./</nowiki>
 
=== Installation ===
 
aptitude update
aptitude install linux-image-vserver linux-headers-vserver util-vserver
