>  Calls to 'nvidia-smi'  fail inside a container even if access to a GPU has been granted. Moreover, access to /dev/nvidiactl is actually required for a container to do anything useful with a GPU even if it has access to it.
>     
> We should grant/revoke access to /dev/nvidiactl as GPUs are added and removed from a container in the Nvidia GPU isolator.
