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.
