Virtuozzo Containers is software, that is used to generate virtual servers on a physical machine. It allows VPS accounts to be generated and managed separately of one another, so each one can have its own Operating System in addition to a fixed and guaranteed amount of system resources, including CPU time, disk space, physical memory, and the like. You'll be able to start, stop or restart the server, to install a variety of software packages, to perform various maintenance tasks, to create firewall rules and even to reset the entire hosting server to its original state using a very intuitive world-wide web interface. You can also keep track of the used and the available resources and on the active processes, to have an idea if the eventual development of your sites will require a package upgrade too. Virtuozzo gives you complete control over your VPS and you're able to manage everything conveniently, even if you don't have much experience.
