OpenVZ is a free and open source virtualization tool that allows you to create virtual private servers (VPS) on your dedicated server. It gives you the ability to run virtual operating systems with “containers” and is regarded as the open source equivalent of Parallels’ Virtuozzo Containers.
WebVZ is essentially a web-based control panel for OpenVZ that makes it easier to manage your virtual private servers. It is light weight (less than 300KB), runs on its own web server, and makes use of SQLite for its database.
WebVZ allows dedicated server administrators to manage their VPS containers from within their web browsers, giving them the ability to: create containers, start, stop, restart, and destroy containers, create configuration files, execute commands inside containers, assign root passwords, backup containers, copy OS templates from one machine to another, monitor container’s resources, set ownership of containers, and much more.
Future versions of the software will include user access modules, managing multiple servers on one screen, and prioritizing containers.
WebVZ requires Ruby on Rails and SQLite to run on a server, both of which are easily installed on most Linux distributions. You can download the latest version from the project’s website.
