Chapter 7. Network Functions Virtualization: Concepts and Architecture

It has been found useful in many installations to use an operating system to simulate the existence of several machines on a single physical set of hardware. The IBM VM/370 operating system is one example. This technique allows an installation to multiprogram several different operating systems (or different versions of the same operating system) on a single physical machine. The dynamic-address-translation hardware allows such a simulator to be efficient enough to be used, in many cases, in production mode.
