What are Vservers

The [http://linux-vserver.org Linux VServer Project] provides Linux kernel-based virtual servers running on a single piece of hardware.

Vservers are very useful for quickly setting up a set of restricted services for testing or production use.

Vservers are not as popular as the similar [http://www.xen-source.com XEN] Hypervisor, but help you a lot, if you have to administrate a large number of servers and services.

While it will take some time until XEN ist integrated into Ubuntu, Vservers are available now.

Installation

Installation is quite simple - you need:

• Kernel with Vserver patch
• util-verver
• vserver-debiantools

You can install these package if you add the following lines to your sources.list:

deb      http://ubuntu.uni-klu.ac.at/ubuntu.uniklu/  breezy  uniklu
deb      http://ubuntu.uni-klu.ac.at/ubuntu.uniklu/  breezy  uniklu-vserver

#deb-src http://ubuntu.uni-klu.ac.at/ubuntu.uniklu/  breezy  uniklu
#deb-src http://ubuntu.uni-klu.ac.at/ubuntu.uniklu/  breezy  uniklu-vserver

The uniklu archives are signed - if you want get rid of apt-get warnings: {{{$ wget http://ubuntu.uni-klu.ac.at/uniklu-debuild.pub $ sudo apt-key add uniklu-debuild.pub }}}

To install the vserver kernel and utils enter:

# apt-get install linux-image-2.6.12-10-686
# apt-get install util-verver vserver-debiantools

You should get the following revisions

The vserver-debiantools do not work 100% but should help you the setup your first vserver - see [http://support.uni-klu.ac.at/Vserver Uniklu Vserver Info]

The kernel and binaries are available for i386 and amd64 and yes you can setup 32bit i386 Vservers running on an amd64 Kernel.
