Oracle VM VirtualBox (formerly Sun VirtualBox, Sun xVM VirtualBox and innotek VirtualBox) is a virtualization software package for x86 and AMD64/Intel64-based computers from Oracle Corporation as part of its family of virtualization products. It was created by innotek GmbH, purchased in 2008 by Sun Microsystems, and now developed by Oracle. It is installed on an existing host operating system as an application; this host application allows additional guest operating systems, each known as a Guest OS, to be loaded and run, each with its own virtual environment.

Backward compatibility, 5

To enjoy the past without limiting your life progress, install the past as virtual machines in the present.

The attraction of virtualizing older operating systems is that it throws off the eternal yoke of backwards compatibility. Instead of bending over backwards to make sure you never break any old APIs, you can build new systems free of the contortions and compromises inherent in guaranteeing that new versions of the operating system never break old applications.

You cannot start a new chapter of your life if you keep re-reading the last one.

The past is a good place to visit but a bad place to stay.
