server virtualization Last modified: Monday, December 25, 2006
The partitioning of a physical server into smaller virtual servers. In server virtualization the resources of the server itself are hidden, or masked, from users, and software is used to divide the physical server into multiple virtual environments, called virtual or private servers. One common usage of this technology is in Web servers. Virtual Web servers are a very popular way of providing low-cost web hosting services. Instead of requiring a separate computer for each server, dozens of virtual servers can co-reside on the same computer. There are several ways to create a virtual server, with the most common being; virtual machine, operating system-level virtualization, and paravirtual machine.

VMware: The Virtual Desktop, The Virtual Server Virtual computers are often better than real ones. When I was younger and a systems analyst for IBM's System/370 mainframe, all my work centered on virtual machines; thanks to the design of the mainframe hardware, my software never "saw" the real hardware, but merely a VM image, common to all System/370 models, that provided a consistent runtime environment not only for me, but for hundreds of simultaneous user sessions.
