Error 43

YEP... if you own a NVIDIA GPU and you use Virtual Machines it is very probably that you meet this error. If not, don't worry I will explain what it mean.

Do you know what is a virtual machine? No?
Well, you can think about as a sandbox, you can run a Operation System inside that sandbox and do whatever you want, like dangerous experiements without damaging your real Operation System. IT PROTECTS YOUR OPERATION SYSTEM, NOT YOU. IF YOU DO SOMETHING DANGEROUS/ILLEGAL INSIDE A VIRTUAL MACHINE... YOU ARE STILL TRACKABLE.

So let's immagine you are running a virtual machine, for this example you have a Linux Machine and you are running a Windows VM, and you want to do a GPU-intensive workload such as gaming (Linux Host that doesn't work well with wine) or video rendering (using specific software such as Premiere PRo).

You will soon discover that you can passthrough your GPU, while installing the NVIDIA drivers or on device manager you will see the "Error 43" and the gpu-device shutdown. What doesn't mean passthrough? Well, you are linking your GPU to the VM so it can use the video card full power.

NVIDIA on the past introduced a check on their CONSUMER products to block this features because they wanted it exclusively for their enterprise cards such as QUADRO.

BUT: Recently NVIDIA announced the enabling of this feature again on our consumer cards on the newest beta drivers!

NVIDIA BLESSING
Should we be happy? I mean this feature was already there and blocked at once on the past... so we are just receiving back what we had.

What do you think?
