Hypervisor

A hypervisor (or virtual machine monitor, VMM, virtualizer) is a kind of emulator; it is 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.

Hardware assisted virtualization

Hardware assisted virtualization uses features that were added to processors such as Intel VT-x or AMD-V.

Hypervisor types and examples
