A virtual machine (VM) is an environment usually a program or operting system, which does not physically exist but is created within another environment. In this context, a VM is called a "guest" while the environment it runs within is called a "host" while the environment it runs within is called a "host." Virtual machines are often created to execute an instruction set different than that of the host environment
