Hypervisor & There Types

Hi guys,

Today I m telling about “Hypervisor & types of Hypervisor”. Most of the times we get confused in hypervisor and Hyper-v(Microsoft Proprietry) and thinks that both are same. But it becomes easy to understand after reading this article. Hope it will be useful to you..

Hypervisor

A hypervisor is a thin virtualization platform that allows multiple operating systems to run on a computer at the same time.

The hypervisor manages the virtual machine’s access to physical resources.

Hypervisor’s are currently classified as two types:

Type -1 : Bare metal Hypervisor  (Ex: VMware ESX Server 4 )

Type -2 : Hosted Hypervisor  (Ex: Microsoft Virtual Server 2005 R2)

Type -1 

Bare Metal Hyper visor

Bare metal OS Virtualization platforms install the hypervisor directly on to the hardware.

·         VMware ESX

·         Microsoft Hyper-V

·         Citrix Xenserver

Type -2

Hosted Hypervisor

Host-based OS virtualization platforms require the hypervisor to run on the installation of an underlying host operating system like windows Server 2003, Linux or MACOSX.

·         Vmware Server, workstation & Fusion

·         Microsoft Virtual server 2005 R@, Virtual PC

·         Parallels
