spent a whole night to risk my stable system and tested the vgpu unlock.

In short, it works.
My set up is 3900X + 128GB RAM + GTX1080 (single GPU)
So I have to use the merge driver approach

Before using vGPU my GPU is wholely passthrough to windows guest.
With vGPU set up, I need to setup desktop mode in proxmox, and pass a vgpu to windows and change it to P6000.

The performance is terrible. especially requiring setting up looking glass to obtain the frame buffer.

After 30 minutes, I start to revert back to my original setup. But I have already install too much junk in proxmox, which make the restoration extremely difficult.

Now I am going to try another combination. I have a spare 1050ti and would like to use it for 4 x 1GB gpu for VM.
And the main gpu to passthrough to a single vm.

Problem is both are nvidia and blacklisting driver may be difficult.

Any utdate on this one?
Now I have tested using vGPU on 1050ti, and uses 1080 to complete passthrough to a single VM.
It runs perfectly fine but needed to make sure to use a compatible version of driver (I used 460).
Both host and client need the same version of driver for compatibility.

It tested a 2GB vRAM profile which runs GTAV fine.

just upgraded to 5.13 kernel and broke the vgpu driver.
And reinstalling driver did not work.
