nVidia GRID does NOT work for vGPU.
Let me say that again, GRID does not work for vGPU.
Ask me how I know (insert sarcasm emoji)
I have a long email thread of trying to get it configured with the help of a few RH folks.
It does NOT do vGPU.
You need a card like a Tesla P4.

Hello Michal,

many thanks for your response. 

Are you sure that there is no vGPU support? Please check lines below

Hi Reza,
it’s nvidia’s doc, you would have to talk to them if you have more questions. All I understand from that doc (it’s just little more below on the same page) is that they explicitly say that K1 and K2 do not support vGPU. This might be a licensing limitation or temporary or anything else, I don’t know.

Thanks,
michal

The NVIDIA Grid K2 is GRID capaable.

Many thanks!
Reza

The page says K1 and K2 do not support vGPU so you could only do Host
Device Passthrough of the whole GPU

That’s only for vgpu which it doesn’t support, so you do not see any mdev
