+ | == Downloading == | ||
+ | |||
+ | The precreated ISO image is available directly from [http://download.openvz.org/livecd/ download.openvz.org/livecd/] or any of the [[download mirrors]]. | ||
+ | |||
+ | {{KernelDownloadTableHead}} | ||
+ | {{DownloadTableRow|path=http://download.openvz.org/livecd|file=CentOS-4.4-OpenVZ-i386-LiveCD.iso|size=}} | ||

+ | {{KernelDownloadTableTail}} | ||
+ | |||
+ | 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 [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-base CD you'll be able to choose the kernel to boot: <tt>ovz9rh</tt>, <tt>ovz18</tt>, <tt>ovz18rh</tt>, <tt>ovz20</tt>, <tt>linux</tt> (original CentOS kernel). | ||
+ | |||
+ | == 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 [[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 /var/lib/vz. | ||
+ | |||
+ | 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 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}}. But it '''works''' on CentOS-based LiveCD! | ||
