Virtuozzo Containers is software, that is used to generate virtual servers on a physical hosting server. It allows VPS accounts to be created and handled separately of each other, so each can have its very own Operating System as well as a fixed and warranted amount of resources, such as CPU time, disk space, physical memory, et cetera. You'll be able to start, stop or restart the server, to set up many different software packages, to do many different maintenance tasks, to set up firewall rules and even to reboot the entire hosting server to its initial state through a very intuitive world-wide web interface. In addition, you can keep an eye on the used and the available resources and on the active processes, in order to have an idea if the eventual development of your websites will require a package upgrade too. Virtuozzo will give you full control over your VPS and you can control everything conveniently, even if you don't have much experience.
