Owl update
Here you can find OpenVZ Live CD image. It is based on Knoppix 5.1.1images. Live CD is a great way to test drive the OpenVZ technology without a need to actually install it on your machine.

== Burning ==
== Booting ==
Just insert the fresh CD into your CD-ROM and reboot. In some cases you have to modify your BIOS settings in order to enable booting from a CD.
If you use CentOS-based CD you'll be able to choose the kernel to boot: <tt>ovz9rh</tt>, <tt>ovz18</tt>, <tt>ovz18rh</tt>, <tt>ovz20</tt> or <tt>linux</tt> (original CentOS kernel).
== Using ==
== 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}}.
You can work around it by mounting some filesystem (<tt>ext2</tt>, <tt>ext3</tt>, <tt>tmpfs</tt>) to <tt>/var/lib/vz/private</tt> directory.
On CentOS-based LiveCD <tt>tmpfs</tt> is mounted on this directory automatically during the booting.
== 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 ===
This CD is based on CentOS 4.4 Live CD and contains the following OpenVZ packages:
* '''kernels''':
** original CentOS 4.4 kernel without virtualization (2.6.9-42.livecd.c4)
** 2.6.9-023stab044.4
** 2.6.18-028stab035
** 2.6.18-028stab035-rhel5

** vzrpm44-4.4.1-22.5
** vzrpm43-4.3.3-7
** vzpkg-2.7.0-18
* '''template metadatas''':
** vztmpl-centos-4-2.0-2
** vztmpl-fedora-core-3-2.0-2
** vztmpl-fedora-core-4-2.0-2
** vztmpl-fedora-core-5-2.0-2
* '''precreated templates''':
** centos-4-i386-minimal
** fedora-core-5-i386-minimal
** debian-3.1-i386-minimal
A number of original CentOS packages were removed (<tt>openoffice</tt>, <tt>gimp</tt>, etc.) in order
to free disk space for OpenVZ packages and templates.

* CentOS 4 minimal
* Fedora Core 5 minimal
It also contains all the software from the original Knoppix 5.1.1 CD, excluding:
