Udemy Free: Course in Spanish on creating Linux virtual machines with VirtualBox

Windows is the most popular and most used operating system so far.

But being honest, This popularity is based on the fact that it comes pre-installed in the vast majority of desktops and laptops on the market..

So there are no more options? The answer is yes. Mainly there is Mac OS, Apple's proprietary operating system found (exclusively) on their computers.

There is also Linux, which can be installed on almost any computer with multiple versions each one specifies in a certain area.

But, change operating system is not very easy to say, It requires having certain experience and knowledge to make the change without losing information and without leaving our computer useless in the process.

Even so, there is an easy way to test other operating systems without having to completely change our computer, we talk about virtualization with VirtualBox.

VirtualBox is a cross-platform virtualization application. Installs existing Intel or AMD based computers, whether they run the operating systems (SO) Windows, Mac OS X, Linux u Oracle Solaris.

Secondly, Expands the capabilities of your existing computer so that it can run multiple operating systems, within multiple virtual machines, at the same time.

For example, you can run Windows and Linux on your Mac, run windows server 2016 on your Linux server, run Linux on your Windows PC, etc., all together with your existing applications.


You can install and run as many virtual machines as you want. The only practical limits are disk space and memory.

Oracle VM VirtualBox is deceptively simple but also very powerful.

Can be run anywhere, from small embedded systems or desktop machines to data center deployments and even cloud environments.
