Virtual machine - Operating system virtual machine

In general terms, a virtual machine in computer science is software that creates an environment between the computer platform and the end user in which the end user can operate software. Specifically, the term virtual machine has several distinct meanings: Virtual machine - Definitions. Virtual machine - Original meaning. The original meaning of virtual machine is the creation of a number of different identical execution environments on a single computer, each of w ...

Virtual machine - Original meaning. The original meaning of virtual machine is the creation of a number of different identical execution environments on a single computer, each of which exactly emulates the host computer. This provides each user with the illusion of having an entire computer, but one that is their "private" machine, isolated from other users, all on a single physical machine. The host software which provides this capability is often referred to as a virtual machine monitor or hypervisor. Virtua ...

Virtual machine - Emulation of the underlying raw hardware. Since each user can run whatever operating system they want, this type of virtual machine allows users to do things like run two different operating systems (sometimes referred to as "guests") on their "private" virtual computers. Also, experimental new versions of operating systems can be run at the same time as older, more stable, versions, each in a separate virtual machine. The process can even be recursive; IBM debugged new versions of its virtual machine operating system, VM, in a virtual ...
