Total unRAID noob, need help passing through GTX 980 ti to Windows 10 VM

m1a8x2 · September 1, 2017

Hi all,

I've recently got my new PC built and installed unRAID. I have been successful in creating a Windows 10 VM, but am unable to get my 980ti passed through. When I change the video and audio in the VM's settings, I get no video signal to my monitor.

I've done the following:

Turned on PCIe ACS Override to isolate the gpu in an IOMMU group
Set the IGPU to default in the bios
Tried the GPU in both PCIe slots of the board

My hardware:

ASRock z270 Extreme4
Intel i7-7700
EVGA GTX 980 TI 6gb Superclocked+ ACX 2.0+
32gb G.Skill DDR4-2400

I'm not sure what to try next, so any suggestions would be appreciated. I'm away from the server now, but will post my VM's XML and IOMMU groups later tonight.

Hey,

I am in a similar situation. I have 2 unRAID machines, and I'm looking to get VM's up on them soon my self, but I'm having some difficulty getting video output on the one I'm working at at work with more server style hardware. I'll be playing with my home set up this weekend to see if I can make any headway there with different hardware.

I'm in a similar position as m1a8x2 here as I have tried almost everything I've see on the forums here or in Spaceinvader One's videos on youtube.

My hardware is:
Mobo: TYAN - S5396
CPUs Dual Xeon 3.0ghz

GFX GeForce GTX 760 ( I do have other options and cards I can use)

16gb ECC RAM PC2-5300f

The only issue I KNOW I have with my hardware is that it beeps at me if I have a gfx card in the first PCIe slot when I try to boot it. But it seems just fine in the other PCIe slot until I turn on the VM.

Now I did run in to issues getting the IOMMU enabled on my mobo at the beginning of my adventure at work here, but I updated the BIOS and turning on the intel vt-d didnt disable the nic's on my board anymore haha.

Here is one of my VM's XML I did try an unedited gpu bios, and an edited one.

And sorry m1a8x2 I don't mean to hijack your thread, I'm just in a very similar place.

I wont be back at work till monday. But I'm fairly stuck. I have a few different VM's loaded up and ready to go, and nothing will pass through the GPU. Tried SeaBIOS and ovmf, and so far just hitting a wall.

Thanks for any help!

@Koitosake no worries! I hope we are both able to find a solution here.

Your problem is that you have a PCI bridge included with the graphics card. You did not list the error it is giving you, which is probably a monitor initialization error or whatever the standard one is. You will have to isolate the PCI bridge away from the graphics card to have any shot at getting it to work. And if your board does not have it's own video output, then you've either got to follow one of @gridrunner's videos about how to use a single video card in an unRaid system (I think he has one of those vids) or get another cheap-o card for unRaid to use.

You need to determine if it is a passthrough problem or windows problem (most likely windows based on your statement.)

Try to create a linux vm or any other blank no OS vm with the gpu and see if it will give you the boot screen. If doing linux (ubuntu or something) see if it will load up. Then you know it is a windows problem and not a server problem.

Both of you: you need to start your vm with the gpu assigned, then after it fails to work, go to Tools>Diagnostics and post the complete zip file.

I've also attached the zip from my diagnostics.

I also tried creating a new Ubuntu VM, assigning a disk size and passing through the GPU for video and sound. When I start the VM I still see no video output from my card.

So out of curiosity, I added another Windows 10 VM and this time chose SeaBIOS. I passed through the GPU for video and sound and started it... BOOM. I have video output from the GPU to the TV. I'm going to destroy the other VM and reinstall using the new template.

Was just going through your post, saw vbios in the xml and ovmf. Was just about to recommend reinstall using seabios.

Thank you for taking the time to help me out. I'll report back if I run into any more issues... still learning as I go.

Did you stub the 980ti (graphics and audio) in the syslinux file?

No? I don't even know how or why I'd do that. Should I?

Thomas van Dalen · September 5, 2017

Thomas van Dalen · September 5, 2017

Yes, you will. Otherwise unraid will assign a driver to it and it'll be "locked" and not able to be passed through. By stubbing the device, it'll make it available to be passed through.

see here (instructions are for a network card, but its the same principle): Stubbing

you'll need to:

stub_ids=10de:17c8,10de:0fb0

you can get to edit the syslinux.cfg file in the gui by selecting the "flash" disk from the dashboard. If you dont feel comfortable editing it yourself, paste it here.
