Hypervisor

"A hypervisor is a software technology used in virtualization, which allows several operating systems to run side-by-side on a given piece of hardware.

"Unlike conventional virtual-computing programs, a hypervisor runs directly on the target hardware's "bare metal," instead of as a program in another operating system. This allows both the guest OSes and the hypervisor to perform that much more efficiently.
