The core package is, since version 4 in December 2010, free software under GNU General Public License version 2 (GPLv2).

In December 2019, VirtualBox started supporting only hardware-assisted virtualization, dropping support for Software-based one. Oracle Corporation acquired Sun in January 2010 and re-branded the product as 'Oracle VM VirtualBox'. Sun Microsystems acquired Innotek in February 2008. Specifically, Innotek developed the 'additions' code in both Windows Virtual PC and Microsoft Virtual Server, which enables various host–guest OS interactions like shared clipboards or dynamic viewport resizing. Innotek GmbH also contributed to the development of OS/2 and Linux support in virtualization and OS/2 ports of products from Connectix which were later acquired by Microsoft. In January 2007, based on counsel by LiSoG, Innotek GmbH released VirtualBox Open Source Edition (OSE) as free and open-source software, subject to the requirements of the GNU General Public License (GPL), version 2. VirtualBox was first offered by Innotek GmbH from Weinstadt, Germany, under a proprietary software license, making one version of the product available at no cost for personal or evaluation use, subject to the VirtualBox Personal Use and Evaluation License (PUEL). For some guest operating systems, a 'Guest Additions' package of device drivers and system applications is available, which typically improves performance, especially that of graphics and allows changing the resolution of the guest OS automatically when the window of the virtual machine on the host OS is resized. It supports the creation and management of guest virtual machines running Windows, Linux, BSD, OS/2, Solaris, Haiku, and OSx86, as well as limited virtualization of macOS guests on Apple hardware. There are also ports to FreeBSD and Genode. VirtualBox may be installed on Windows, macOS, Linux, Solaris and OpenSolaris. Created by Innotek, it was acquired by Sun Microsystems in 2008, which was in turn acquired by Oracle in 2010. Oracle VM VirtualBox (formerly Sun VirtualBox, Sun xVM VirtualBox and Innotek VirtualBox) is a free and open-source hosted hypervisor for x86 virtualization, developed by Oracle Corporation.
