Are you sure that nvidia-smi is relevant to the K1/K2 devices? Does it
work on the host? I wouldn't be surprised if a system management
interface tries to use backdoors that are not available in a VM. Are
there other tests you can do to check whether the device is otherwise
available? Also, I'm curious to see what these cards look like, could
you provide an 'sudo lspci -vvv' of the host system? Thanks,
Alex
