[vbox-dev] utlizing the nvidia card of the host machine in the vm

[Klaus Espenlaub]

Rajiv,

currently VirtualBox doesn't support GPU passthrough. It supports some 
basic PCI passthrough functionality (only on Linux), but GPUs beat it.

Besides - do you have a 2nd graphics card in the system? GPU passthrough 
(if it'd work) can't do miracles like sharing one PCI device between the 
host and the VM.

What works with many applications is the (guest additions based) 3D 
support which you enabled. Of course it also uses the host's 3D card 
(provided there are usable drivers), by passing the OpenGL stream.
