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

CD contents
This CD contains the following OpenVZ packages:
- kernel 2.6.18-028stab027
- 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
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.
Downloading
The precreated ISO image is available directly from download.openvz.org/livecd/ or any of the download mirrors.
| File | Size |
|---|---|
| KNOPPIX_V5.1.1-OPENVZ-CD-2007-01-04-EN.iso | 683 MB |
| KNOPPIX_V5.1.1-OPENVZ-CD-2007-01-04-EN.iso.md5 | 77 B |
| KNOPPIX_V5.1.1-OPENVZ-CD-2007-01-04-EN.iso.asc | 189 B |
Note that .md5 and .asc files does not need to be copied to the CD-R; they are here to check the authentity of the iso file. Package_signatures#Checking_files has some info on this topic.
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 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.
Using
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.
Limitations
Since this is a live CD, 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 VEs 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 /var/lib/vz.
OpenVZ disk quota does not work on LiveCD at the moment due to OpenVZ Bug #558, so df in VE shows ludicrous values if quota is on.
