virt: Add vboxguest driver for Virtual Box Guest integration
This commit adds a driver for the Virtual Box Guest PCI device used in Virtual Box virtual machines. Enabling this driver will add support for Virtual Box Guest integration features such as copy-and-paste, seamless mode and OpenGL pass-through. This driver also offers vboxguest IPC functionality which is needed for the vboxfs driver which offers folder sharing support.

This is a driver for the Virtual Box Guest PCI device used in
|
||||
Virtual Box virtual machines. Enabling this driver will add
|
||||
support for Virtual Box Guest integration features such as
|
||||
copy-and-paste, seamless mode and OpenGL pass-through.
|
||||
|
||||
This driver also offers vboxguest IPC functionality which is needed
|
||||
for the vboxfs driver which offers folder sharing support.
|
||||
|
||||
If you enable this driver you should also enable the VBOXVIDEO option.
|
||||
|
||||
Although it is possible to build this module in, it is advised
|
||||
to build this driver as a module, so that it can be updated
|
||||
independently of the kernel. Select M to build this driver as a
|
||||
module.
