OpenVZ Software Available for Latest Linux Kernel 2.6.20
HERNDON, Va., March 28, 2007 -- Keeping in step with the Linux kernel
development, the OpenVZ project (http://openvz.org <http://openvz.org/> )
today announced availability of its operating system (OS) server
virtualization software for the most recent stable Linux kernel 2.6.20 --
introduced last month.
This new Linux kernel includes a number of bug fixes and improvements, along
with support for the latest hardware.
"Linux 2.6.20 is also the basis for the next Ubuntu distribution, which
potentially would enable us a smooth transition to add OpenVZ
virtualization," said Kir Kolyshkin, manager of the OpenVZ project. "With
this latest release of OpenVZ software, we've made a number of improvements
to benefit our users in the open source community."
The OpenVZ software for Linux kernel 2.6.20 includes improvements in the
- Support for read-only bind mounts, which allows a read-only view into a
read-write file system. This allows for greater levels of control and
enhances security by only allowing specified parts of file systems to be
- Namespaces technology, resulting from on-going work on Linux kernel
containers virtualization, is now used by OpenVZ software.
New I/O prioritization feature that makes it possible to set priorities
for each virtual environment so that some can be set as high priority for
disk access, and others as lower priority. This solves the problem of
distributing I/O throughput (which can be a performance bottleneck) across
all virtual environments.
The new OpenVZ kernel software can be downloaded here,
<http://openvz.org/download/kernel/devel/> Also, users can access helpful
installation instructions from the OpenVZ wiki,
http://wiki.openvz.org/Quick_installation. The site serves as a forum to
gain and share knowledge about OpenVZ and includes documentation and a
knowledge base with helpful advice.
About the OpenVZ Project
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 11,000 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
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,
