Hypervisor

Hypervisors allow for improved utilization of a system’s resources as well as more IT mobility. A hypervisor lowers the amount of physical server space, energy consumption, and maintenance needed to support many virtual machines.

Hypervisors are typically divided into two types: – Type 1 hypervisors, commonly referred to as native or bare metal hypervisors, operate exclusively on the host computer without the need for any additional software or operating systems. Virtual machines operate atop a type 1 hypervisor, which serves as an OS in and of itself. In this case, the host computer can only be utilized to run the virtual machines. – Type 2 hypervisors, also known as hosted or embedded hypervisors, operate as software programmes inside the host computer’s operating system. Multiple guest VMs can operate on the same host with the help of a type 2 hypervisor, but it is unable to directly access the hardware and resources of the host. It is frequently used in homes or testing facilities.
