The Guest Additions for Windows, Linux, Solaris, OpenSolaris, and OS/2 guests include a special video-driver that increases video performance and includes additional features, such as automatically adjusting the guest resolution when resizing the VM window [38] and desktop composition via virtualized WDDM drivers.
It ships with VirtualBox Guest Additions, and driver improvements to improve performance as a guest operating system. [ 72 ] The difficulties in efficiently running OS/2 have, at least once, created an opportunity for a new virtualization company.
The physical, "real-world" hardware running the VM is generally referred to as the 'host', and the virtual machine emulated on that machine is generally referred to as the 'guest'. A host can emulate several guests, each of which can emulate different operating systems and hardware platforms.
As with KQEMU, VirtualBox runs nearly all guest code natively on the host via the VMM (Virtual Machine Manager) and uses the re-compiler only as a fallback mechanism – for example, when guest code executes in real mode. [22] In addition, VirtualBox did a lot of code analysis and patching using a built-in disassembler to minimize recompilation.
However, installing Virtual Machine Additions from an older Microsoft virtualization product works for some guest OSes.

GPU virtualization refers to technologies that allow the use of a GPU to accelerate graphics or GPGPU applications running on a virtual machine.GPU virtualization is used in various applications such as desktop virtualization, [1] cloud gaming [2] and computational science (e.g. hydrodynamics simulations).
The virtual machine additions in older VPC versions and the virtual machine integration features in Windows Virtual PC contain precompact ISO images for the first step in supported guest systems. [13] Third-party products also use VHD file format. Oracle VirtualBox, part of Sun xVM line of Sun Microsystems supports VHD in
