What are two types of hypervisors?

There are two types of hypervisors:Type 1 hypervisor: hypervisors run directly on the system hardware – A “bare metal” embedded hypervisor,Type 2 hypervisor: hypervisors run on a host operating system that provides virtualization services, such as I/O device support and memory management.

What is virtualization and how it works?

Virtualization is the process of creating a software-based, or virtual, representation of something, such as virtual applications, servers, storage and networks. It is the single most effective way to reduce IT expenses while boosting efficiency and agility for all size businesses.

Why do we need VM?

The main purpose of VMs is to operate multiple operating systems at the same time, from the same piece of hardware. Without virtualization, operating multiple systems — like Windows and Linux — would require two separate physical units. … Hardware requires physical space that isn’t always available.

What are the 2 types of full virtualization systems?

There are two types of full virtualization: bare metal virtualization (aka native virtualization) and hosted virtualization. With bare metal virtualization, the hypervisor runs directly on the underlying hardware, without a host OS.

Where is virtualization used?

Storage virtualization is commonly used in storage area networks. Server virtualization is the masking of server resources — including the number and identity of individual physical servers, processors and operating systems — from server users.
