− | == Burning ==
| |
− | | |
− | After downloading the image, you have to burn it to the actual media, i.e. a CD-R or CD-RW disk. The process depends on the actual OS and CD burning software that you have, and the exact details are out of scope of this article.
| |
− | | |
− | If you don't know how to burn the ISO image to CD-R, try [http://www.knoppix.net/wiki/Downloading_FAQ#Q:_I_have_downloaded_the_ISO_file._How_do_I_burn_the_ISO.3F_How_is_the_ISO_supposed_to_be_burned.3F this document].
| |
− | | |
− | == 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 ==
| |
− | 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 these are live CDs, 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.
