OpenVZ is container-based virtualization for Linux. OpenVZ creates multiple secure, isolated containers (otherwise known as VEs or VPSs) on a single physical server enabling better server utilization and ensuring that applications do not conflict. Each container performs and executes exactly like a stand-alone server; a container can be rebooted independently and have root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files. For more information about the technology and how it differs from the others like Xen, VMware etc., see [[introduction to virtualization]], {{PDFlink|[[download:doc/openvz-intro.pdf|doc/openvz-intro.pdf]]|73 KB}} or [[wikipedia:OpenVZ]].

Andd it's fixed! It looks like they updated the newer version of vcmmd, and didn't roll back to the older version as a &quot;fix&quot;, so that's good at least.

Seems to be a real oversight here. Hopefully it will get fixed asap.

OpenVZ is container-based virtualization for Linux. OpenVZ creates multiple secure, isolated containers (otherwise known as VEs or VPSs) on a single physical server enabling better server utilization and ensuring that applications do not conflict. Each container performs and executes exactly like a stand-alone server; a container can be rebooted independently and have root access, users, IP addresses, memory, processes, files, applications, system libraries and configuration files. For more information about the technology and how it differs from the others like Xen, VMware etc., see introduction to virtualization, doc/openvz-intro.pdf (73 KB) or wikipedia:OpenVZ.

OpenVZ is free open source software, available under GNU GPL.

OpenVZ is the basis of Parallels Virtuozzo Containers, a commercial virtualization solution offered by Parallels. OpenVZ project is supported by Parallels.

Installation and usage

OpenVZ is easy to install if you already have Linux installed on your machine. See quick installation for installation info. Alternatively, you can try a live CD to test drive the technology without a need to install anything.

A comprehensive doc/OpenVZ-Users-Guide.pdf ( 1.3 MB) is a good start. This wiki also has a lot of information (use search function, see list of all categories or list of all pages.

Support

Please read the documentation before asking questions. Check the FAQ, use Google, search both this wiki and the forum. If this doesn't help, ask on either forum or a mailing list.

Please report all bugs to OpenVZ bugzilla.

Commercial support is also available, email sales@openvz.org for details.

Testimonials

I'm curious. For the past few months, people@openvz.org have discovered (and fixed) an ongoing stream of obscure but serious and quite long-standing bugs.

How are you discovering these bugs?
