A hypervisor, also known as a virtual machine monitor (VMM) or virtualizer, is a type of computer software, firmware or hardware that creates and runs virtual machines. A computer on which a hypervisor runs one or more virtual machines is called a host machine , and each virtual machine is called a guest machine .

The software or firmware that creates a virtual machine on the host hardware is called a hypervisor or virtual machine monitor. [2] Software executed on these virtual machines is separated from the underlying hardware resources.
The physical, "real-world" hardware running the VM is generally referred to as the 'host', and the virtual machine emulated on that machine is generally referred to as the 'guest'. A host can emulate several guests, each of which can emulate different operating systems and hardware platforms.
[8] [9] For some guest operating systems, a "Guest Additions" package of device drivers and system applications is available, [10] [11] which typically improves performance, especially that of graphics, and allows changing the resolution of the guest OS automatically when the window of the virtual machine on the host OS is resized.
