[SOLVED] Problem with GPU Passthrough

Hello everyone,
I'm really banging my head against the wall for the last week or so trying to make my GPU passthrough to work, but I keep getting the error Code 43.

I've read and tried some of the workarounds in this and other threads but nothing seems to work.


So, I'm using a HP workstation:

Machine: Hp Z2 MINI G4
CPU: Intel CoreTM i7
Ram: 16GB
GPU: Nvidia Quadro P1000
SDD: 512 GB SSD for Proxmox

Using Proxmox VE 7.3-3
Guest VM: Windows 10 Pro

Please if someone has any tips on how to make this work, help me :)

Thanks for your kind notes! I encountered a similar issue in Proxmox 7.2.5. Replacing video=efifb:off with initcall_blacklist=sysfb_init in /etc/default/grub indeed resolves the issue.

This indeed resolve my issue with BAR 1 error also, thank you guys.
 
Hey all,

I've been attempting to get integrated gpu passthrough to work the past couple days.
Through extensive searching I came across multiple tutorials online and this thread.

Whenever I start the Win11 VM the entire PVE crashes and requires a hard restart of the host machine.

I have attempted to add the remove/rescan script and the mentioned config modifications.

I am hoping someone may have some insight on something I have missed.

Thanks!

Solved!

Using:
echo 1 > /sys/bus/pci/devices/0000\:09\:00.0/remove
echo 1 > /sys/bus/pci/rescan

You can create a .sh chmod +x and add it to cron

File: /root/fix_gpu_pass.sh

//Note Change "0000\:0X\:00.0" for your GPU PCI ID

#!/bin/bash
echo 1 > /sys/bus/pci/devices/0000\:0X\:00.0/remove
echo 1 > /sys/bus/pci/rescan

Add to cron:

crontab -e

add:

@reboot /root/fix_gpu_pass.sh

Thank You ! This resolved my issue. Thought i would have to replace the GPU.
 
Hey there,

I've been trying to get my 2 gpu's passed through to one VM in proxmox.

Weirdly if they are allocated to separate VM's they work fine (they show up in nvidia-smi at ubuntu terminal or in task manager in windows, and I can run a game). Their IDs are 08 and 09.

However when I try to run them on the same VM (I allocate 08 and 09 to my Windows.P2V) it doesnt even load, I just get a black screen..

They are the same model, Nvidia 2080 OEM's from HP, the reason for dual GPU is NVlink and memory pooling.

The following is the dmesg:

[  682.930353] vfio-pci 0000:08:00.0: No more image in the PCI ROM

Any clue how to go by?
 
I've been doing GPU passthrough for years and I've not had any issues in recent years until today.
I've tried everything in this thread and nothing worked.
I've tried eveything in the wiki and nothing worked.
I've tried all the combinations of what was in thread and what was in the wiki and it didn't work.

I even did a sanity check and removed the gpu and the vm booted just fine.

Finally, I found the issue: I was allocating too much memory.
I lowered the amount down and now everything works.

I'm on PVE 8.04.
 
Hi,

On PVE 8.0.4. AMD 5900x. 2 x Nvidia RTX3090 GPU.

In an Ubuntu 22.04.3 LTS VM, when I first run nvidia-smi, I only see 1 GPU. After doing the following in the VM:

Code: 
sudo nano /etc/modprobe.d/blacklist.conf
# then add


blacklist nvidiafb 
blacklist nouveau


# Save, then run:
sudo depmod -ae 
sudo update-initramfs -u


# then reboot the VM

Repeating nvidia-smi, I now see both GPUs. However, after a proxmox host shutdown and power up, back in the VM I only see 1 GPU, so have to repeat the above prescribed process of blacklisting. i.e. the changes do not stick in the VM after host reboot.

Would be most grateful for any ideas how to resolve, thank you
 
Hello guys. Does anyone use this method (removing GPU from devices) with vendor-reset (AMD RX580), I can't add script to my device, because it's not in the device list?

vendor-reset works fine with RX580. I don't understand what you mean by "removing GPU from devices" and "add script to my device", sorry.
Maybe look at a thread about vendor-reset and RX580, like this one: https://forum.proxmox.com/threads/g...-strange-screen-behaviour.126727/#post-553643
There are lots of other threads about vendor-reset and how to get it working: https://forum.proxmox.com/search/6415725/?q=vendor-reset&o=date

There is a part of code in vendor-reset where I shoul add like this echo 'device_specific' > /sys/bus/pci/devices/<pci_device_id_here>/reset_method, but I think because I use this code I got an error - there is no device in the list (because whithout that code my RX580 doesn't work, but with this code everything is fine, except when GPU is glitching my whole server dies :()
echo 1 > /sys/bus/pci/devices/0000\:0X\:00.0/remove echo 1 > /sys/bus/pci/rescan

You only need to do echo device_specific > '/sys/bus/pci/devices/0000:0X:00.0/reset_method' once, every reboot of the Proxmox host. Use crontab, /etc/rc.local or a hookscript (or type it yourself on the console or use SSH).

Stop doing that. You don't need to do that. That's why you use vendor-reset; to reset the RX580 properly using RX580-specific code. Don't drop the GPU from the PCIe bus like you would with NVidia GPUs when they are used during boot of the Proxmox host. Instead, just let the amdgpu driver load for the RX580; don't blacklist it!

Thx for your help! But when I try to echo device_specific > '/sys/bus/pci/devices/0000:03:00.0/reset_method' I get -bash: echo: write error: Invalid argument Also I've tried to install vendor-reset but when I check it with modprobe vendor-reset I get Module vendor-reset not found in directory /lib/modules/6.5.11-6-pve I remove that code (/sys/bus/pci/devices/0000\:0X\:00.0/remove) but I think it doesn't help me
 
This is what available
apt install pve-headers pve-headers pve-headers-6.2 pve-headers-6.2.16-3-pve pve-headers-6.1 pve-headers-6.2.16-1-pve pve-headers-6.2.16-4-pve pve-headers-6.1.10-1-pve pve-headers-6.2.16-2-pve pve-headers-6.2.16-5-pve
no 6.5.11-6-pve :(

Use proxmox-headers-6.5, which is the new name. (Why so many old and discontinued kernels?)

I don't know what helped, but I remove AMD card from vfio, updated system with apt update, rebooted the system and vendor-reset started to work, but id didn't help in my case, because the whole system still stack when the GPU glithches :( Anyway, I give it a try... Thank you leesteken for your help!
 
Hi, I did set up everithing and it was working like charm. (win 11)
I worked on some other VMs. Today was my free day and I wanted to play some games in my win 11 vm. I got error 43 and bad resolution.

I tried out what I found here, but did not help. My GRUB looks like this:
Code: 
GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_iommu=on"
GRUB_CMDLINE_LINUX="textonly video=efifb:off"

I did roll back a backup, set it fresh up, but no luck so far:-(
