GPU will not survive a reboot
This host has an NVIDIA GPU, but either the nvidia kernel module is not loaded (the GPU is unusable now) or nouveau is not blacklisted. If nouveau is not blacklisted it binds the GPU first on the next boot, the nvidia driver cannot load, nvidia-smi fails, and a marketplace (Vast) host silently de-lists itself. The fix is non-disruptive and only affects the next boot.
