Notes for GPU passthrough
^^^^^^^^^^^^^^^^^^^^^^^^^
When passing through a GPU (be it a full device, or a vGPU), if you want to use
it for displaying, you have to either physically connect a monitor to the
card (if possible), or configure a remote desktop software (e.g., VNC, RDP)
inside the guest and use that.
It is not possible to display the content of the GPU via NoVNC/SPICE on the
{pve} web interface.
If you want to use the GPU for things like OpenCL or CUDA, this is not an issue,
since the application should be able to choose the hardware without using
it as a display.
