[GTX 970 will not work]

Yes I was looking to run it "headless" because I don't have enough PCIe slots for what I'm hoping to do (two pc's) at least not in the right places.  I think it's probably just time to swap mobos to something that works but if I can't figure out the FPS issues I might just go back to windows anyways.  I tried assigning manually to PCIe 5 as well with a smaller card and that didn't work either, it used the GTX 970

EVGA, do you have onboard video on your unraid box?

[GPU passthrough with only one card?]

A little stale in here, has anyone else had any luck with the commands for the nvidia?  I threw my card in the second slot and I get errors with the echo "0000:04:00.0" > ..unbind as well as the cat rom > ...

 

I even tried nano rom and the file is just empty?

Edit: Turns out (from other posts) it's because nvidea doesn't play nice unless you have a dedicated graphics card for unraid.  AMD works fine.  I swapped locations of the HD 6950 and the GTX970 and that makes the 970 work, the question is, has anyone had any luck with the commands from https://lime-technology.com/forum/index.php?topic=43644.15

 

I am getting the same errors as are posted but no one posted how they fixed them

echo "0000:02:00.0" > /sys/bus/pci/drivers/vfio-pci/unbind

this gives me this message "bash: echo: write error: No such device" unless I have the VM running, in which case the screen goes dark (duh)

 

cd /sys/bus/pci/devices/0000:02:00.0/
echo 1 > rom
cat rom > /boot/vbios.rom
echo 0 > rom

 

These do nothing, echo 1 > rom doesn't error out but it also doesn't add anything to the rom file (nothing in nano?)

cat rom > /boot/vbios.rom gives me "cat: rom: Input/output error"

 

Has anyone had success with this? is there another work around?

 

Thanks!

hey everyone, totally fresh on the unraid train.  first build, I have a few video cards, one worked one didn't.  Long story short I bought a GTX 960 and a GTX 970 to replace my pc and the wifes pc and it doesn't go anywhere, just a black screen.  Before I made the leap and bought I had been running my PC on an AMD Radeon HD 6950.  it works perfectly fine on that with the following xml (which I honestly have been trying to figure out what the XML does and have 0 idea).

 

Here is the build info:

Mobo: GA-990FXA-UD5

Video Cards:

GTX 970

GTX 960

Radeon HD 6950

32Gb Memory

2 Cache drives and 5 hard drives

 

VM is set to use SeaBios (don't know what the other one does)

1440fx-2.3 (don't know what the others do)

 

Just looking for what to look at to find out why it will not work with the GTX's.  (Also FYI if I attach the GTX to the HD 6950's VM and boot it it crashes over and over showing "nvlddmkm.sys" as the BSOD reason (System_Service_Exception)
