**Virtual Machine (VM)** is a software program or [[dido:public:ra:xapend:xapend.a_glossary:o:os|operating system]] that not only exhibits the behavior of a separate computer, but is also capable of performing tasks such as running [[dido:public:ra:xapend:xapend.a_glossary:a:application|applications and programs]] like a separate computer.

In other words, a **VM** is a software application that performs most functions of a physical computer, actually behaving as a separate computer system.

A **Virtual Machine**, usually known as a guest, is created within another computing environment referred to as a "host." Multiple virtual machines can exist within a single host at one time.
