Hypervisor & There Types
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..
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)
Bare Metal Hyper visor
Bare metal OS Virtualization platforms install the hypervisor directly on to the hardware.
· VMware ESX
· Microsoft Hyper-V
· Citrix Xenserver
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
