Click on the new to set up the new VM, select the Linux and then Red Hat, since CentOS is the clone of Red Hat and uses a similar architecture.
The 64-bit architecture has been used for this demonstration, so download the software accordingly.
In this article, we will discuss the core architecture, how it is different from others and how to install and configure it on the VirtualBox (demonstration).ĭownload the appropriate version of both the packages. However, it has been clearly adopted by a large number of community members, so it must have some weight over others. The CentOS clearly stands out amongst the others.

In this tutorial, we will show you two ways to install VirtualBox on Ubuntu 20.04: Generally, Virtualbox is used by desktop users as a testing and development environment. Is open-source cross-platform virtualization software that allows you to run multiple guest operating systems (virtual machines) simultaneously.
