Set Up and Run a 64-bit Guest in VirtualBox For instance, if you want to run Linux within Windows, then Windows would be the host and Linux would be the guest. Guest refers to the operating system you will be running within the box. Host refers to the computer you will be running VirtualBox on your computer’s native OS. Two terms you need to learn right away to be able to work with VirtualBox are host and guest. At an enterprise level, rather than running a backup server, a separate mail server, and a separate SharePoint server, each can run in its own virtual instance on a single physical host machine. So rather than building a separate computer to run a different operating system, you only need one. It allows individuals and enterprises to run several functions on a single computer, rather than forcing someone to find the space and the money to have more than one. VirtualBox doesn’t care what you use as long as you configure it properly. We can also use different versions of Linux within Linux or Windows within Windows.

You could run Linux within Windows or the other way round.
