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 Linux-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 ==
== Lucid ==
Kernel Version: 2.6.32


=== Prerequisites ===
Vserver patch: 2.3.0.36.29.4


* 32 Bit Ubuntu Dapper.
Status: experimental
* installed packages:


apt-get install build-essential gcc make g++ libncurses5-dev
=== Known Limitations ===
* linux-image
** CONFIG_AUFS has been disabled


=== Howto Devel 2.6.17.14-vs2.0.2.1-grsec2.1.9 ===
== Karmic ==
Kernel Version: 2.6.31


==== Get the Kernel ====
Vserver patch: 2.3.0.36.19
* 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

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


==== Patch the Kernel ====
Status: experimental
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 ====
=== Known Limitations ===
make # this will take a long time
* linux-image
make install
** CONFIG_AUFS has been disabled
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 ====
== Jaunty ==
Kernel Version: 2.6.28


* boot Kernel
Vserver patch: 2.3.0.36.9
* ''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 ==
Status: experimental


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.
=== Known Limitations ===
* linux-image
** CONFIG_AUFS has been disabled
* linux-headers
** Up to version 2.6.28-11.42~ppa1 the linux-headers package was broken which broke external modules built manually or via dkms (nvidia, virtualbox). If you are experiencing problems with one of those modules please update to the latest package version and rebuild the modules. For modules built via dkms this can be done with:
dkms remove -m <modulename> -v <moduleversion> -k 2.6.28-11-vserver
dkms build -m <modulename> -v <moduleversion> -k 2.6.28-11-vserver
dkms install -m <modulename> -v <moduleversion> -k 2.6.28-11-vserver

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].

== Problems ==
== Repository ==
You can add the following key to your apt keyring:


When you recieve a 'Segmentation fault' error running vserver-utils try useing latest [http://www.fefe.de/dietlibc/ dietlibc]
<nowiki>sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com BB9BFB5B</nowiki>
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.
=== Lucid ===
Feity and up gcc version won't let you compile correctly dietlibc yet.


Add the following line to your sources.list:


== Ubuntu Gutsy Information ==
deb http://ppa.launchpad.net/christoph-lukas/ppa/ubuntu lucid main
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.
deb-src http://ppa.launchpad.net/christoph-lukas/ppa/ubuntu lucid main


To create the guest system, do these commands:
=== Karmic ===
# 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 ==
deb http://ppa.launchpad.net/christoph-lukas/ppa/ubuntu karmic main
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):
  deb-src http://ppa.launchpad.net/christoph-lukas/ppa/ubuntu karmic main
  update-initramfs -k 2.6.22.19-vs2.2.0.7 -c


Look up man 8 update-initramfs for details.
