There are two different types of hypervisors, which are type1 hypervisor and type 2 hypervisor. Type 1 hypervisor which is loaded directly on the hardware; the figure I is an example of type 1 hypervisor. There are VMware ESXi or ESX loaded directly on the physical server. Hyper-V, ESX/ESXi, and XenServer are type 1 hypervisor. Type 2 is loaded into an operating system, which is already running on the hardware like any installed application on your desktop or laptop.

VMware fusion is loaded on a Macintosh system like a MacBook Pro or Mac mini. A type 2 hypervisor doesn’t perform as well as the type 1 hypervisors because the operating system layer is in between the virtualization layer and physical hardware. The consolidation ratio with type 2 hypervisors is much lower than the consolidation ratio with type 1 hypervisor.

One can install so many virtual machines on the same piece of hardware with using a type 2 hypervisor. Type 2 hypervisors are more useful than type 1 hypervisors if you want to run multiple virtual machines at the same time. There is a big benefit to use the type2 hypervisor.
