Hyper-V is a native hypervisor developed by Microsoft; it can create virtual machines on x86-64 systems running Windows. [1] It is included in Pro and Enterprise editions of Windows NT (since Windows 8) as an optional feature to be manually enabled. [2]
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.
PR/SM (Processor Resource/System Manager) is a type-1 Hypervisor (a virtual machine monitor) that allows multiple logical partitions to share physical resources such as CPUs, memory, I/O channels and LAN interfaces; the LPARs can share I/O devices such as direct access storage devices (DASD). Initially, the operator could select either basic ...
System Management Mode (SMM, sometimes called ring −2 in reference to protection rings) [1] [2] is an operating mode of x86 central processor units (CPUs) in which all normal execution, including the operating system, is suspended.
The result of this is XtratuM 2.0 which is type 1 hypervisor that uses para-virtualization. The para-virtualized operations are as close to the hardware as possible. Therefore, porting an operating system that already works on the native system is a simple task: replace some parts of the operating system HAL with the corresponding hypercalls.
The creation and management of virtual machines has also been called "platform virtualization", or "server virtualization", more recently. [2] [3] Platform virtualization is performed on a given hardware platform by host software (a control program), which creates a simulated computer environment, a virtual machine (VM), for its guest software ...
An embedded hypervisor is a hypervisor that supports the requirements of embedded systems. The requirements for an embedded hypervisor are distinct from hypervisors targeting server and desktop applications. An embedded hypervisor is designed into the embedded device from the outset, rather than loaded subsequent to device deployment.
In computing, a client hypervisor is a hypervisor that is designed for use on client computers such as laptops, desktops or workstations, rather than on a server. It is a technique of host virtualization which enables the parallel execution of multiple operating systems (or virtual machines ) on shared hardware.
