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:
| + | == CD contents == |
| | | | |
| − | * The "official" [http://www.openwall.com/Owl/ Openwall GNU/*/Linux (or Owl)] disc image (live & installable, maintained). | + | This CD contains recent OpenVZ packages, including: |
| − | * One based on CentOS 4.4 (abandoned). | + | * kernel 2.6.18-028stab031 |
| − | * One based on Knoppix 5.1.1 (abandoned). | + | * vzctl 3.0.16 |
| | + | * vzquota 3.0.9 |
| | + | plus the number of precreated templates: |
| | + | * Debian 3.1 minimal |
| | + | * CentOS 4 minimal |
| | + | * Fedora Core 5 minimal |
| | | | |
| − | == Download ==
| + | It also contains all the software from the original Knoppix 5.1.1 CD, excluding: |
| | + | * OpenOffice |
| | + | * GIMP |
| | + | * Frozen Bubble |
| | + | The above packages were taken out to make some room for OpenVZ packages. |
| | | | |
| − | 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]].

| − | 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].
| + | Upon the successful boot, a browser window with some helful 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]]. |

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}}.

| − | On CentOS-based LiveCD <tt>tmpfs</tt> is mounted on this directory automatically during the booting.

| − | === 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 ===
