I started using Proxmox some days ago and put a considerable amount of hours into trying to get my Intel A310 GPU to work properly for passthrough to a VM, or, to be more precise: to hand it back to the system after the VM is shutdown. I am a Linux novice as well but learned a lot these past days. I read many threads from here, level1techs, reddit, and some other sites but wasn't able to solve my problem. Huge props to leesteken for helping out so many people with PVE.
Problem desc:
I can passthrough my dGPU (Intel A310) and its audio (they sit on separate buses) to a Windows 11 VM and everything works as expected. As soon as I power off the VM, the GPU/VGA part of the device doesn't get handed back correctly, only the audio part does. Thus the GPU can't be used for anything anymore and I have to restart the host.
Interesting observations:
Because of my above observations, I tried some things around the audio device (04:00.0):
Any and all help/ideas are appreciated. I might go with a fresh install next but I don't know if it's even worth it. I set up my server follwing the Perfect Media Server tutorial with MergerFS/Snapraid on host and documented all steps and code. Reinstalling should be fine but I would still like to avoid it.
System info: latest PVE/Kernel @ AMD Ryzen 9600X on Asus Pro WS B850M-Ace SE w/ Intel A310 dGPU in Pciex16_1 and ASM1166 in Pciex16(X4)_2.

Interesting observations:
- The problem only appears when I pass through both the VGA and the audio parts of the A310. If I pass through only the VGA, I can shutdown the VM without losing access to the GPU on host. The lack of sound isn't feasible though, since I want to use this VM for display output on my TV.
- Like many noobs do, I used
apt upgradeat some point and thought that might've broken something. Now I think it's more likely that I only passed through the VGA part before I did that and the problem thus didn't occur yet. I haven't done a fresh install yet. - When I pass through the GPU (VGA/audio) with the manually added ARGS, I can use the noVNC from the Proxmox GUI, while when I pass through from Proxmox GUI, the noVNC makes no connection and contents are only displayed through dGPU HDMI on my monitor.
Because of my above observations, I tried some things around the audio device (04:00.0):
- Added vfio bind option to modprobe.d/vfio.conf (
options vfio-pci ids=8086:4f92), and reverted because it didn't help. Also blacklisted snd-hda-intel driver via pve-blacklist.conf, and reverted as well. (incl.update-initramfs -u -k all, reboots) - Added snd-hda-intel.conf with options
snd-hda-intel enable_msi=1just to try it out because I thought it maybe did something (real tired already) - Using the following ARGS for the VM config instead of GUI PCI passthrough options:
args: -device vfio-pci,host=03:00.0,addr=10.0,multifunction=on,x-vga=on,rombar=0 -device vfio-pci,host=04:00.0,addr=10.1 - Using hookscripts to do the binding/unbinding, since it's not happening automatically with ARGS instead of hostpci0/1.
- Using different combinations of PCI passthrough options from PVE GUI (Rombar on/off, pcie on/off, all functions on/off, mapped/raw) for "both devices"
- Edited GRUB with
iommu=pt, also tried without. Usedupdate-grubeach time, then reboot. - Adding vfio modules to /etc/modules
- Isolating the GPU from host through early binding to vfio and disabling vga. I still want to use the GPU for other tasks and the Windows VM isn't running all the time.

Any and all help/ideas are appreciated. I might go with a fresh install next but I don't know if it's even worth it. I set up my server follwing the Perfect Media Server tutorial with MergerFS/Snapraid on host and documented all steps and code. Reinstalling should be fine but I would still like to avoid it.
System info: latest PVE/Kernel @ AMD Ryzen 9600X on Asus Pro WS B850M-Ace SE w/ Intel A310 dGPU in Pciex16_1 and ASM1166 in Pciex16(X4)_2.
