Hyper Visor

In computing, a HyperVisor (also: virtual machine monitor) is an OsVirtualization platform that allows multiple operating systems to run on a host computer at the same time. The term usually refers to an implementation using full virtualization. Hypervisors are currently classified in two types:

The term hypervisor apparently originated in IBM's CP-370 reimplementation of CP-67 for the IbmSystemThreeSeventy?, released in 1972 as VM/370. The term hypervisor call referred to the paravirtualization interface, by which a "guest" operating system could access services directly from the (higher-level) control program – analogous to making a "supervisor call" to the (same level) operating system. (The term 'supervisor' refers to the operating system kernel, which on IBM mainframes runs in supervisor state.)
