Keeping in step with the Linux kernel development, the OpenVZ
project 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
The OpenVZ software for Linux kernel 2.6.20 includes
improvements in the following areas:
- 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 made writable.
- Namespaces technology, resulting from on-going work on Linux
kernel containers virtualization, is now used by OpenVZ
- A 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. Also, users
can access helpful installation instructions from the OpenVZ wiki. The
site serves as a forum to gain and share knowledge about OpenVZ and
includes documentation and a knowledge base with helpful
