3] Understand about Hypervisors

The hypervisor is a hardware virtualization technique that allows multiple guest operating systems (OS) to run on a single host system at the same time.

It creates a virtualization layer that separates the actual hardware components - processors, RAM, and other physical resources - from the virtual machines and the operating systems they run.

Types of Hypervisors

• Type 1 Hypervisors, also known as bare-metal or native.

• Type 2 Hypervisors, also known as hosted hypervisors.

Type 1 Hypervisor --> a Type 1 hypervisor is a layer of software installed directly on top of a physical server and its underlying hardware.

Examples

• VMware vSphere with ESX/ESXi

• Microsoft Hyper-V

• Citrix Hypervisor

Type 2 Hypervisor --> a Type 2 hypervisors run inside the physical host machine's operating system, which is why they are called hosted hypervisors

Examples

• Oracle VM Virtualbox

• VMware Fusion

• Windows Virtual P
