Background
A virtual machine refers to a particular piece of software in the architecture of computer science that creates an environment between a computer platform and an end user who operates other software based on the environment created by the virtual machine's software. A Virtual Machine (VM) is an emulator of a computer system that provides the functionality of a physical computer by software emulating a complete computer system with the functionality of a complete hardware system, operating in a completely isolated environment. The virtual machine provides an environment for the simulation of the mirror image, provides a hardware simulation environment required by an original system, and also provides conditions for the simulation and the operation.
