OS Virtualization in its Simplest Way

摘要

Virtuozzo is an OS virtualization and Server automation solution. With Virtuozzo, you can create independent VPSes (Virtual Private Servers) on one server by virtualizing the Host OS, ie running Windows 2003 on your server would mean that all Virtual Servers run Win 2003 but each VPS performs like a stand-alone machine with its own IP address, memory, processes configuration files, etc. Also every VPS has its unique administrator, which has total control over that VPS. With Virtuozzo, you can increase hardware utilization of your servers by placing multiple VPSes on a single hardware node. The Virtuozzo layer makes sure that all VPSes sharing the OS and Server's hardware are completely isolated. The VPSes use Virtuozzo network adapter as their gateway to communicate with outside networks.
