Release: OpenVZ for Linux kernel 3.0.25

The open source OS virtualization solution OpenVZ (formerly OpenVirtuozzo), supported by Parallels, is now available in version 3.0.25. This version is an update of version OpenVZ serves as the basis of Parallels Virtuozzo Containers

OpenVZ can be installed on top of Linux distributions as a patch and is a container-based virtualization platform for Linux, meaning that it does virtualization on the OS level. It creates multiple secure isolated containers on a single physical server to ensure that applications do not conflict, one of the biggest advantages of container-based virtualization is that the VM’s running on top of it, do not have to be modified or as it is called "enlightened" in order to run.

Changes in this version include:

  • vzctl start/runscript: add ability to set per-container kernel version (/etc/vz/osrelease.conf) now providing support for Fedora 14 etc.
  • Removed cron scripts to handle cleanup and reboot
  • Introduced vzeventd daemon to handle cleanup and reboot
  • vzctl set –pci_{add,del}: add the ability to delegate PCI devices to a container.

The full changelog is available on the OpenVZ wiki.
