Ubuntu – VirtualBox on Ubuntu 16.04 not using Nvidia memory

nvidia-graphics-cardubuntu 16.04virtualbox

I'm using a DELL M3800 with a Nvidia Quadro K1100M with 2GB VRAM.

Before installing the Nvidia drivers using

apt-get install nvidia-331 nvidia-settings nvidia-prime

VirtualBox 5 was displaying only the 256 MB VRAM of the integrated Intel Video adapter.

Now I installed the Nvidia drivers but VirtualBox still only provides the 256MB.

How can I provide the Nvidia card VRAM in VirtualBox?
Is there a way to scan for updated host hardware?

Update:

I'm speaking about this VirtualBox settings dialog but not about video settings inside the VM.

You cannot! VirtualBox does not care how much physical VRAM you have. It sets aside the virtual VRAM from your physical memory.
