[GPU Passthrough doesnt work after Updating to unRAID 6.9]

Jeez, I'm sorry friends. Not sure where to go from here.

 

@DoeBoye It sounds like our problems are a little different. I was never able to load the VM unless the Nvidia Driver wasn't installed, otherwise it would freeze on the loading screen, then boot loop.

@giafidis & @DoeBoye If you aren't using the vBios from your GFX card I recommend using Space Invader Ones script to pull it. The script is here: https://github.com/SpaceinvaderOne/Dump_GPU_vBIOS

 

Use the User Scripts plugin, add the script and modify the first section, run it once and then assign the vBios in your VM.

Same as yours. What do you normally use to remote into your VM? Maybe try a fresh VM install and run the script.

 

I would agree, try a new VM. Make sure Hyper-V is set back to Yes as well.

 

Here is what my VM looks like in 6.9.0, perhaps you'll see something that will help:

----------- ANSWER --------

 

For easy reading, this was the answer needed. In the event that you get mmap errors on passing through the rom, or you install the nvidia drivers and get errors like the above, try running the following in command line and try again

 

echo 0 > /sys/class/vtconsole/vtcon0/bind
echo 0 > /sys/class/vtconsole/vtcon1/bind
echo efi-framebuffer.0 > /sys/bus/platform/drivers/efi-framebuffer/unbind

 

I added these to a user script that triggers on first array boot up. I have now successfully remove a gpu i no longer need from my system and am able to reboot unraid and have the vm auto start on the primary gpu

 

Don't mean to Necro, but this solved it for me. Thanks a lot.

 

If you are looking at your VM Logs by clicking on your VM and clicking Logs, and you're seeing:

2021-03-06T06:32:32.186442Z qemu-system-x86_64: vfio_region_write(0000:09:00.0:region1+0x1be6ba, 0x0,1) failed: Device or resource busy

Try the fix above. It worked for me.

 

The Hardware I'm running:

ASUS Prime X570-Pro

Ryzen 7 3700x

ASUS Strix GTX 1060 Gaming

 

Best of luck.

You two are not the only ones. I upgraded to 6.9 and the VM was working fine. I upgraded my hardware from Intel to AMD a few days later, I'm in the same boat you two are now. Rolling back to try 6.8.3 now...

 

Intel 6700k

ASUS Maximus Hero VIII

 

upgraded to:

 

Ryzen 7 3700x

ASUS Prime X570-Pro

 

GPU is an ASUS GTX 1060.

Edit:

I resolved my issue. Having dug deeper I found the following in my VM Log:

2021-03-06T06:32:32.186442Z qemu-system-x86_64: vfio_region_write(0000:09:00.0:region1+0x1be6ba, 0x0,1) failed: Device or resource busy

 

Some searching yielded another thread:

 

Adding a user script to User Script Plugin that runs when the array starts seems to have solved my issue, I was able to successfully boot into Windows 10 VM with the GTX 1060 passed through. I have installed the drivers successfully.

 

The script:

#!/bin/bash
echo 0 > /sys/class/vtconsole/vtcon0/bind
echo 0 > /sys/class/vtconsole/vtcon1/bind
echo efi-framebuffer.0 > /sys/bus/platform/drivers/efi-framebuffer/unbind

 

Edit 2:

For clarification, my VM would not load on 6.8.3 or 6.9.0 with GTX 1060 as my primary and only gpu in the system. This script fixed the problem for me in both 6.8.3 and 6.9.0.
