Strange, according to that the driver still is not loaded
$ sudo nsenter --mount=/run/snapd/ns/lxd.mnt env PATH=/snap/lxd/current/bin:${PATH} LD_LIBRARY_PATH=/snap/lxd/current/lib nvidia-container-cli info
nvidia-container-cli.real: initialization error: nvml error: driver not loaded
According to lspci -knn the driver is loaded:
44:00.0 VGA compatible controller [0300]: NVIDIA Corporation GK208B [GeForce GT 710] [10de:128b] (rev a1)
Subsystem: ZOTAC International (MCO) Ltd. GK208B [GeForce GT 710] [19da:5360]
Kernel driver in use: nvidia
Kernel modules: nvidiafb, nouveau, nvidia_drm, nvidia
Edit: Also the output of nvidia-smi is different now as I configured a different GPU for passthrough:
s$ nvidia-smi
