VirtualBox

VirtualBox is an x86 virtualization software package, originally created by German software company InnoTek, now developed by Oracle as part of its xVM virtualization platform. It is installed on an existing host operating system; within this application, additional operating systems, each known as a Guest OS, can be loaded and run, each with its own virtual environment.

Host or Guest
OS/2 can act both as a host operating system or as a guest operating system when running VirtualBox. Some constraints apply to what you can do and specifically HOW you do things depending on the availability and combinations of "hosts" and "guests":
 * as a Host OS: In this case, OS/2 is your machines operating system. By installing VirtualBox for OS/2 and eComStation, you will be able to run different operating systems as "virtual machines" on your PC.
 * as a Guest OS: Running OS/2 as a guest means that your PC is actually running some other operating system (like Linux, Windows, ...) and OS/2 will be available as virtual machines.

VirtualBox for OS/2
This software is needed if you want to run different operating systems from within your OS/2 system (it will thus give you a VirtualBox 'host' on your machine). Whereas, if you intend to run OS/2 as a virtual machine on a different operating system environment (e.g. "run OS/2 on a Windows machine"), you will need to download the appropriate VirtualBox version (in this case the Windows version).
