Hi there @aleksey.izmailov,
I don’t have a good solution for you here, just a few observations.
RTX 6000 Ada is our newest workstation card, so you will definitely need the latest possible drivers.
You will likely have purchased this card from one of our partners with proper (enterprise?) support, that means you should talk to them first about using the device in a virtual machine environment. I am not really sure that they all support this as the GeForce GPUs do.
Finally since I am not the expert, you might find more help over in the vGPU forums, where there are also discussions on normal pass-through usage of our GPUs, not only licensed vGPU setups.
Thanks!
