Now we know which services and servers we want to have, but before we install them, let's quickly review how we can create VMs and connect them to our lab network. We will use Oracle VirtualBox virtualization software for that purpose, because it is free and powerful at the same time.
As we said earlier, we will use Oracle VM VirtualBox as the virtualization platform for hosts. VirtualBox is a powerful, feature-rich, high-performance virtualization solution for enterprise as well as home use. VirtualBox is freely available as open source software under the terms of the GNU General Public License (GPL) Version 2.
You can always refer to the official VirtualBox documentation to get more information (https://www.virtualbox.org/wiki/Documentation).
VirtualBox can be launched on different operating systems and supports a large number of guest operating systems including but not limited to Windows and Linux.
