What is VirtualBox?
VirtualBox is a free, open-source and cross-platform software that lets you create, run, and manage virtual machines on your system. VirtualBox was originally developed by Innotek GmbH and released in 2007. The company was later bought by Sun Microsystems. With Oracle VM VirtualBox you can create one or more VMs on a single physical server. Virtual machines are computers that use the hardware components of the host computer, each running its own operating system. VB supports the installation of MS Windows, Linux, BDS, and MS-DOS on the installed VMs.
