Vagrant is a handy and easy-to-use Virtual Machine tool that can be used within your command-line interface. In a nutshell, it makes it easy to create and configure lightweight, reproducible developer environments.

In this mini course, you will learn all about virtualization. You will learn how to set up a Vagrant environment, build your own VM, as well as Vagrant commands which you can use from the command line.

In the latter half of the course, you will learn how to work with vagrantfile, networking, and data sharing. In all, this is your crash course for understanding the fundamentals of Vagrant.

A Guide to Vagrant and Virtual Machines

# Hypervisors

The piece of software that enables virtualization is called a hypervisor, which is also known as a Virtual Machine Manager (VMM). The hypervisor makes it possible to run more than one Virtual Machine at a time by using the same hardware resources.
# Types of hypervisors

* Type 1 hypervisor
* Type 2 hypervisor

Yes, you read it right, there are only two types of hypervisors: type 1 and type 2.


## Type 1 hypervisor

The type 1 hypervisor directly runs on the hardware, which is why it is called the bare-metal hypervisor. The type 1 hypervisor acts as the operating system for the physical machine. This setup is mostly used for server-side virtualization because the hypervisor has low hardware requirements to support its own functions.
When using the type 1 hypervisor, a no host OS is involved. The virtual OS runs within the hypervisor, and the virtual (guest) OS are independent of each other. Some examples of type 1 hypervisors are Microsoft Hyper-V, VMware, ESX, and Citrix Xenserver.




In this lesson, we'll learn about the types of hypervisors.
