There are two types of hypervisors: type 1 and type 2 hypervisor.
In type 1 hypervisor (or native hypervisor), the hypervisor is installed directly on the physical
server. Then instances of an operating system (OS) are installed on the hypervisor. Type 1
hypervisor has direct access to the hardware resources. Therefore they are more efficient than
hosted architectures. Some examples of type 1 hypervisor are VMware vSphere/ESXi, Oracle VM
Server, KVM and Microsoft Hyper-V.
In contrast to type 1 hypervisor, a type 2 hypervisor (or hosted hypervisor) runs on top of an
operating system and not the physical hardware directly. answer 'Type 1 hypervisor runs directly
on the physical hardware of the host machine without relying on the underlying OS' big advantage
of Type 2 hypervisors is that management console software is not required. Examples of type 2
hypervisor are VMware Workstation (which can run on Windows, Mac and Linux) or Microsoft
Virtual PC (only runs on Windows).
