mind1 Posted April 18, 2019 Share Posted April 18, 2019 I'm trying to get an Ubuntu VM running with 3 Tesla K80s. I'm running Unraid 6.7.0-RC7. I've passed through all 6 devices (each K80 appears as 2 devices), but after configuring everything inside of the VM nvidia-smi only displays 1 GPU. The strange thing is that lspci displays all 6. If I install the nvidia drivers into the Unraid host, nvidia-smi there displays all 6 as expected. Is there anything special that has to be done to pass these GPUs through to the guest VM?

mind1 Posted April 18, 2019 Author Share Posted April 18, 2019 So I just noticed the following in my dmesg log: [ 9.283359] NVRM: This PCI I/O region assigned to your NVIDIA device is invalid: NVRM: BAR0 is 0M @ 0x0 (PCI:0000:07:00.0) [ 9.283360] NVRM: The system BIOS may have misconfigured your GPU.

mind1 Posted April 18, 2019 Author Share Posted April 18, 2019 For anyone looking for an answer, I switched from OVMF to SeaBIOS and it seems to work just fine. Not sure why OVMF didn't work though. Anyone want to take a stab at that? Quote Link to comment
