The Guest Additions enable you to control and monitor guest execution in ways other than those mentioned above. Generic host/guest communication channels See Section , &# Seamless windows&# for details. With this feature, the individual windows that are displayed on the desktop of the virtual machine can be mapped on the host's desktop, as if the underlying application was actually running on the host. Please see Section , &# Resizing the machine's window&# also.įinally, if the Guest Additions are installed, 3D graphics and 2D video for guest applications can be accelerated see Section , &# Hardware-accelerated graphics&#. The video resolution in the guest will be automatically adjusted (as if you had manually entered an arbitrary resolution in the guest's display settings). In addition, with Windows, Linux and Solaris guests, you can resize the virtual machine's window if the Guest Additions are installed. While the virtual graphics card which VirtualBox emulates for any guest operating system provides all the basic features, the custom video drivers that are installed with the Guest Additions provide you with extra high and non-standard video modes as well as accelerated video performance. For details, please refer to Section , &# Shared folders&#. Much like ordinary Windows network shares, you can tell VirtualBox to treat a certain host directory as a shared folder, and VirtualBox will make it available to the guest operating system as a network share, irrespective of whether guest actually has a network. These provide an easy way to exchange files between the host and the guest.

To make this work, a special mouse driver is installed in the guest that communicates with the 'real' mouse driver on your host and moves the guest mouse pointer accordingly.

You will only have one mouse pointer and pressing the Host key is no longer required to 'free' the mouse from being captured by the guest OS. To overcome the limitations for mouse support that were described in Section , &# Capturing and releasing keyboard and mouse&#, this provides you with seamless mouse support.
