Detailed explanation-1: -Using virtualization software, you can run multiple operating systems on one physical machine. The technology is now mainstream enough that it is a built-in feature in Windows 7 Professional (and above) and in Windows Server 2008 R2.
Detailed explanation-2: -Hardware virtualization, which is also known as server virtualization, allows hardware resources to be utilized more efficiently and for one machine to simultaneously run different operating systems.
Detailed explanation-3: -A hypervisor, also known as a virtual machine monitor or VMM, is software that creates and runs virtual machines (VMs). A hypervisor allows one host computer to support multiple guest VMs by virtually sharing its resources, such as memory and processing.
Detailed explanation-4: -Hypervisors allocate resources and ensure VMs play nicely while sharing the same computing power. Sometimes, the hypervisor is also referred to as a virtual machine monitor (VMM). The hypervisor is essential for enabling a single physical computer to run multiple independent operating systems simultaneously.
