Each operating system controlled by the hypervisor is called a guest OS, and the hypervisor's operating system, if any, is called the host OS. Because it stands between the guest OS and hardware you can have as many different guest OSs as your system can handle; you can even have different types (e.g. Windows, OS X, Linux).

A virtual machine (VM) allows a different operating system to be executed inside the confines of its distinct computing environment within a window similar to those used for other programs. As it is often separated from the rest of the system, the virtual machine cannot make any unapproved modifications to the host computer.

A Virtual Machine (VM) is a compute resource that uses software instead of a physical computer to run programs and deploy apps. One or more virtual “guest” machines run on a physical “host” machine. Each virtual machine runs its own operating system and functions separately from the other VMs, even when they are all running on the same host. A virtual computer system is known as a “virtual machine” (VM): a tightly isolated software container with an operating system and application inside. Each self-contained VM is completely independent. Putting multiple VMs on a single computer enables several operating systems and applications to run on just one physical server, or “host.”. How to manage virtual memory in an OS; Bottom line; How virtual memory works.
