Type 1 and Type 2 Virtualization

Can someone please highlight Type1 and Type2 of Virtualization as I am bit confused?

Hi @Abdul_Rehman,
The primary contributor to why hypervisors are segregated into two types is because of the presence or absence of the underlying operating system. Type 1 runs directly on the hardware with Virtual Machine resources provided. Type 2 runs on the host OS to provide virtualization management and other services.

Type 1 hypervisors

A Type 1 hypervisor runs directly on the host machine’s physical hardware, and it’s referred to as a bare-metal hypervisor. The Type 1 hypervisor doesn’t have to load an underlying OS. With direct access to the underlying hardware and no other software – such as OSes and device drivers – to contend with for virtualization, Type 1 hypervisors are regarded as the most efficient and best-performing hypervisors available for enterprise computing.

Type 2 hypervisors

A Type 2 hypervisor is typically installed on top of an existing OS. It is sometimes called a hosted hypervisor because it relies on the host machine’s preexisting OS to manage calls to CPU, memory, storage and network resources.

Great, Got it. Thanks!!
