In this article, we will explore Step by Step how to make a virtual machine, providing a detailed technical guide for those who wish to delve into the fascinating world of virtualization.

1. What is a virtual machine and how does it work?

A virtual machine is software that emulates to a computer physical and allows you to run several operating systems or applications on the same computer. It works by creating a virtual, isolated and separate environment of the operating system main, where they can be installed and run different systems operating systems and software without affecting the operation of the physical equipment.

The virtual machine is made up of several main elements, such as the hypervisor, which is responsible for managing the resources of the physical computer and assigning them to the virtual machines. It also has a set of files, known as images, that contain and operating system and the applications to be installed on the virtual machine.

To create a virtual machine, virtualization software, such as VirtualBox or VMware, is required to manage and configure virtual machines. Once the virtualization software is installed, a new virtual machine can be created by selecting the operating system and configuring the allocated resources, such as the amount of RAM and storage space. After creating the virtual machine, you can boot and install the operating system and necessary applications, just as if you were using a physical computer.
