Hypervisor

Posted: August 4, 2012 in Live in a Cloudy World, Microprocessor, Virtualization

Based on the latest Blog posts about Virtualization on Intel Microprocessor, and the VMM (Virtual Machine Monitor) the Hypervisor is the main component for the Virtualization. The Hypervisor most likely is called the VMM (Virtual Machine Manager), I think that this is the component that is managing the Virtual Machine Monitor of the processor to gain 3 main things:

  1. Equivalence, for executing the applications running on the guest OS as it is running on a normal PC
  2. Hardware Resource Control, this feature mainly prevents the guest OS from changing or accessing any kind of the configuration system
  3. Efficiency, that means that all the instructions of the guest OS must be executed simply and in an easy way without any interfering of the Hypervisor or the Virtual Machine Monitor.

Types of Hypervisor:

  • Bare metal Hypervisor

    The bare metal is the hypervisor that can control directly the Hardware resources and can easily manage the resources for different Guests that want to run their applications.

  • Hosted Hypervisor

     

    The hosted Hypervisor is a hosted hypervisor on an operating system that acts like an application that the operating systems executes its instructions.
