Owl update
Here you can find OpenVZ Live CD images. Live CD is a great way to test drive the OpenVZ technology without a need to actually install it on your machine.
We offer three live CDs at the moment. : * The first one is based on Knoppix 5.1.1, the second one is based on CentOS 4.4, and the third one is the "official" [http://www.openwall.com/Owl/ Openwall GNU/*/Linux (or Owl)] CD disc image (live & installable, maintained).* One based on CentOS 4.4 (abandoned).* One based on Knoppix 5.1.1 (abandoned).
== Download ==
The ISO images for Owl are available from the [http://www.openwall.com/Owl/DOWNLOAD.shtml Openwall FTP mirrors], such as via the links below (which use a specific fast mirror). The precreated ISO images for Knoppix and CentOS are available directly from [http://download.openvz.org/livecd/ download.openvz.org/livecd/] or any of the [[download mirrors]]. The ISO images for Owl are available from the [http://www.openwall.com/Owl/DOWNLOAD.shtml Openwall FTP mirrors], such as via the links below (which use a specific fast mirror).

== Using ==
With the Owl CD, brief instructions (not OpenVZ specific yet) will be printed to the console, right before dropping you to a shell prompt. Then you will need to proceed with [http://openwall.info/wiki/Owl/usage-examples/OpenVZ/getting-started instructions for getting started with OpenVZ on Owl, as found on the Openwall wiki].
With the Knoppix (and CentOS?) CDs, upon successful boot, a browser window with some helpful hints will appear to help you start using OpenVZ. The latest version of that document is also available on this wiki: [[Getting started with OpenVZ live CD]].
== Limitations ==
Since this is a these are live CDCDs, everything is created in RAM, i.e. is not persistent. If you will create a number of VEs, they will not be available after the reboot.
A number of [[VE]]s that you can create using this live CD greatly depends on the amount of RAM your machine has, since the system uses RAM instead of a hard disk. On a 1 gigabyte RAM machine you can create about 5 VEs. To work around this, you have to have a disk partition mounted to <tt>/vz/private/</tt> for CentOS-based CD and to <tt>/var/lib/vz/private</tt> for KNOPPIX-based CD.
OpenVZ disk quota does not work on LiveCD at the moment due to {{Bug|558}}, so <code>df</code> in [[VE]] shows ludicrous values if quota is on.
Because of it on Owl and CentOS 4.4 LiveCD disk quota is switched off by default.
Checkpointing (and consequently live migration) doesn't work on KNOPPIX LiveCD at the moment due to {{Bug|606}}.
== CD contents ==
=== Owl DVD contents ===
This DVD image (about 800 MB in size) uses the following OpenVZ components:
* kernel 2.6.18-431.el5.028stab123.1.owl2 (latest unreleased/unofficial post-EOL revision from OpenVZ's RHEL5 branch as of May 2018, with minor changes for Owl)
* vzctl 3.0.23 (with minor enhancements and customizations by ALT Linux and Owl teams)
* vzquota 3.0.12
The live system is a full install of the Owl userland, including networking clients, servers, as well as "development" tools and libraries (C, C++). It also includes installable packages, the installer program, full source code, and the build environment. Unfortunately, it does not include pre-created container templates, but you may either configure networking (with "setup") and download a pre-created template to RAM, or you may use "make vztemplate" to create a new template of the Owl userland right on the CD-booted system.
=== CentOS CD contents ===
* Frozen Bubble
The above packages were taken out to make some room for OpenVZ packages.
== Changelog ==
* 29 January 2010, added Owl
* 5 July 2007, version based on CentOS 4.4
* 7 May 2007, initial version based on Knoppix 5.1.1
