Virtualisation enables us to set up multiple virtual machines over one physical computer. The benefits of virtualsation are countless, from being able to create virtual representation of different machines, to efficiently use the currently available hardware. Clearly a virtual machine, like any real computer, needs an operating system. In this context it’s called a Guest OS, as opposed to the one running on real hardware, called Host OS.
