Virtuozzo Containers is software, that's used to make virtual servers on a physical server. It allows VPS accounts to be created and controlled independently of each other, so each of them can have its own OS in addition to a fixed and guaranteed amount of system resources, which include CPU time, disk space, physical memory, et cetera. You will be able to stop, start or reboot the server, to set up different software packages, to perform numerous maintenance tasks, to set up firewall rules and even to reset the entire server to its initial state using a very user-friendly online interface. In addition, you can monitor the used and the available system resources and on the active processes, to have an idea whether the eventual development of your web sites will require a package upgrade as well. Virtuozzo gives you complete control over your VPS and you will be able to manage everything with ease, even when you do not have a lot of experience.
