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. | 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.

+ | === Owl CD contents === | ||
+ | This CD uses the following OpenVZ components: | ||
+ | * kernel 2.6.18-128.2.1.el5.028stab064.8 (from OpenVZ's "rhel5" branch, with very 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. | ||
