OpenVZ Virtualization on 'Live CD' Without Requiring Hard Disk
The OpenVZ project today announced availability of its operating system (OS) server virtualization software as a modified version of the Knoppix 5.1.1 bootable Live CD so that users can test drive the OpenVZ software without changes to their computer or installing anything on their hard disk.
"This is the first time we've been able to offer our open source OS virtualization in this format, which provides users a risk-free way to test OpenVZ, along with the Knoppix distribution," said Kir Kolyshkin, manager of the OpenVZ project. "Knoppix is very popular with hobbyists and Linux enthusiasts who can now try our open source virtualization software, which is in keeping with our objective to promote OS virtualization."
Knoppix is a bootable Live system on CD, consisting of a representative collection of GNU/Linux software, automatic hardware detection, and support for many graphics cards, sound cards, SCSI and USB devices and other peripherals. It is not necessary to install anything on a hard disk and there is no need to have a Linux distribution installed.
The OpenVZ software for Knoppix 5.1.1 can be downloaded here, http://openvz.org/download/livecd. Also, users can access helpful instructions from the OpenVZ wiki, http://wiki.openvz.org/Getting_started_with_OpenVZ_live_CD. The site serves as a forum to gain and share knowledge about OpenVZ and includes documentation and a knowledge base.
The OpenVZ project freely distributes and offers support to its users, promoting operating system virtualization through a collaborative, community effort. Supported by SWsoft, the OpenVZ project serves the needs of the community developers, testers, documentation experts, and other technology enthusiasts who wish to participate in and accelerate the technology development process. OpenVZ is open source software that is used as the basis for the SWsoft Virtuozzo virtualization software product.
Since going into full production late in 2005, the OpenVZ project has been very active with the user community with more than 12,000 message posts on its support Forum. The OpenVZ website attracts tens of thousands of visitors each month as more businesses and individuals explore and contribute to the leading open source operating system virtualization project.
OpenVZ is operating system server virtualization software technology, built on Linux, which creates multiple isolated, secure virtual environments on a single physical server – enabling greater server utilization and superior availability with fewer performance penalties. The virtual servers ensure that applications do not conflict and can be re-booted independently.
With the power of today's processors, hardware is often under utilized. With virtualization technology, the server can effectively be split into many small ones, each running its tasks so that the whole server is utilized more efficiently.
OpenVZ software can be used to help consolidate servers and increase server utilization rates, or for creating "sandboxes" for test and development, or when sharing resources so that every user can have root access while being kept isolated from each other.
The OpenVZ software comes with user tools that help automate management of virtual servers. With its unique architecture that uses a single operating system instance, the virtual servers perform and execute like independent servers with their own memory, configuration files, users and applications. Each can be re-booted independently. Using template-based application deployment provides a simple way to get new virtual servers up and running in minutes and OpenVZ can run several times more virtual servers per CPU than other virtualization technologies. Also, the OpenVZ project maintains a blog site discussing virtualization technology, which can be accessed here, http://blog.openvz.org.
