Virtuozzo Containers is a software solution, that's used to create virtual servers on a physical server. It allows VPS accounts to be set up and managed independently of one another, so each one can have its own Operating System plus a fixed and guaranteed amount of system resources, including CPU time, disk space, physical memory, et cetera. You'll be able to stop, start or reboot the server, to install different software packages, to perform various maintenance tasks, to create firewall rules and even to reset the entire server to its original state by using a very intuitive web interface. You may also monitor the used and the available system resources and on the running processes, so as to have an idea when the eventual growth of your websites will require a package upgrade as well. Virtuozzo offers you complete control of your VPS and you're able to manage everything easily, even if you don't have much experience.
