Virtuozzo Containers is an efficient virtualization solution, which is used to install virtual machines functioning independently of each other on a physical server. Every single VPS has an OS of its own and it can be controlled from the Virtuozzo Control Panel where you can find lots of options which will give you complete control over the whole machine. Using an intuitive, point & click graphical interface, you can start, stop or reboot your machine any time, to do a number of maintenance tasks, to recover a back up copy, to set up various server-side software modules, as well as a lot more. The resource monitoring software tool will give you in-depth info about the overall performance of the VPS, which means that if you expand your sites, you can easily find whether the current configuration can handle the additional load, or whether you will require an upgrade. If needed, you can also reinstall the VPS container to its default state, resetting any changes you've made.
