Software or firmware responsible for hosting and managing virtual machines. For the purposes of PCI DSS, the hypervisor system component also includes the virtual machine monitor (VMM).

A hypervisor, also called virtual machine manager (VMM), is one of many hardware virtualization techniques that allow multiple operating systems, termed guests, to run concurrently on a host computer. [..]

Software that arbitrates and controls VM access to the actual underlying hardware.

In virtualization technology, hypervisor is a software program that manages multiple operating systems (or multiple instances of the same operating system) on a single computer system. The hypervisor [..]

a form of control software layer that enables multiple operating systems to run on the same physical hardware. The oldest hypervisor is IBM's VM — but this only runs on S/370-style hardware (wher [..]

The software that coordinates the low-level interaction between virtual machines and the underlying physical computer hardware.

A hypervisor is a hardware virtualization technique that allows multiple guest operating systems (OS) to run on a single host system at the same time. The guest OS shares the hardware of the host comp [..]

Virtualizing software that renders a host invisible to a guest, thus permitting the installation of multiple guests on one host.

A hypervisor is the layer of software that manages communications between virtual machines and the hardware on which they are running at any given moment. It allows multiple operating systems to run s [..]
