Since no other software runs between the hardware and the hypervisor, it is also called the bare-metal hypervisor. Type 1 HypervisorĪ Type 1 hypervisor is a layer of software installed directly on top of a physical server and its underlying hardware.

The sections below explain both types in greater detail. Type 2 Hypervisors, also known as hosted hypervisors.Type 1 Hypervisors, also known as bare-metal or native.There are two types of hypervisors, according to their place in the server virtualization structure: The VMs do not depend on their host hardware and can easily be transferred to another system. Multiple virtual environments on a single server fully utilize the available CPU and memory. Maximize utilization of their computing resources.The fact that the hypervisor allows VMs to function as typical computing instances makes the hypervisor useful for companies planning to: Guest machines do not know that the hypervisor created them in a virtual environment or that they share available computing power. Why Use a Hypervisor?įrom a VM's standpoint, there is no difference between the physical and virtualized environment. No matter what operating system boots up on a virtual machine, it will think that actual physical hardware is at its disposal. Hypervisors emulate available resources so that guest machines can use them. The machine hosting a hypervisor is called the host machine, while the virtual instances running on top of the hypervisor are known as the guest virtual machines. 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. A hypervisor is a crucial piece of software that makes virtualization possible.
