Cannot get nVIDIA GPU to be to become selctable in advanced settings/ virtualization

Got GTX1070

nvidia-msi:

lspci -v | grep nvidia
lscpi -v | grep NVIDIA

Somehow it remains “out of reach’ which is to say it does not appear in 'isolate GPU” in advanced settings, nor slectable when creating a new VM

Any help is greatly appreciated

You can’t isolate the video card if it’s the only GPU in the system.
Do you have another GPU in there?
