Installation
The token file has to be copied! It's not enough to C&P file contents, because there can be special characters.
Linux
curl --insecure -X GET https://<dls-hostname-or-ip>/client-token -o /etc/nvidia/ClientConfigToken/client_configuration_token.tok
service nvidia-gridd restart
nvidia-smi -q | grep "License"
Windows
Download file and place it into C:\Program Files\NVIDIA Corporation\vGPU Licensing\ClientConfigToken.
Now restart NvContainerLocalSystem service.
Troubleshoot
