Virtuozzo Containers is software, that's used to make virtual servers on a physical server. It allows VPS accounts to be generated and handled independently of each other, so each one can have its very own Operating System in addition to a fixed and ensured volume of system resources, including CPU time, disk space, physical memory, and the like. You are able to start, stop or reboot the server, to set up various software packages, to perform many different maintenance tasks, to set up firewall rules and even to reset the entire server to its initial state using a very intuitive web interface.

Virtuozzo gives you complete control of your VPS and you'll be able to control everything effortlessly, even if you do not have a lot of experience.
