Econaut Posted August 19, 2021 Share Posted August 19, 2021 (edited) I was able to boot a Ubuntu VM (OVMF Q35 5.1) with only the video device passed through (no sound counterpart) and the system worked for 2 subsequent boots with 3D acceleration (but no sound). I then added the sound device pass-through and it stopped booting. I made the Space Invader special XML tweak that seems to be a long-standing bug that isn't fixed yet. The system looks like it boots and I can even see the teamviewer alias pop into the list but it is inaccessible and the GPU has no output. I can get it back to booting by removing the sound device and restarting unraid (tested once - I maybe had to boot with VNC vga once first too before reassigning the passthrough GPU). I am booting unraid in UEFI (tried legacy boot also) System has an APU (Ryzen 5 2400G) as primary GPU & passthrough GPU in first PCIe slot IOMMU forced enabled in bios (GPU reserved in unraid for vfio) I have tried with or without the specified ROM vbios file (pulled manually from a bare metal windows boot and the techpowerup utility) VM log: -overcommit mem-lock=off \ -smp

jonp Posted August 27, 2021 Share Posted August 27, 2021 AMD-based GPUs are notorious for having more problems with GPU passthrough. When issues like these occur, you can try doing some online research for your specific GPU to see if there are any additional quirks you can apply, but generally speaking it is far easier to just replace your AMD GPU with an NVIDIA one and use that instead as it tends to have far better success with pass through. All the best, Jon Quote Link to comment
Econaut Posted August 30, 2021 Author Share Posted August 30, 2021 Oh wow your kidding! Everything I read seemed to indicate that AMD GPUs were the easier option because they weren't locked down leading to error 43 and others. I am trying to use a rather rare and probably unpopular card to be sure but I figured since it was enterprise/professional grade it may have better chances. https://www.amd.com/en/products/professional-graphics/radeon-pro-wx-2100 Is there anymore diagnostics that I could provide that may help determine why/what is failing? Like I mentioned, it actually works with pass-through until I add the sound component which seems to be strange and the opposite of what all the other information suggests. Quote Link to comment
nGran Posted March 20, 2022 Share Posted March 20, 2022 (edited) Hey Econaut, Did you manage to resolve you issue? I have the same type of problem with my windows 10 Vm. I am using Nvidia Rtx 3070, and all was fine and running well, video and audio passthrough, until one day I was not able to start my vm. I got stuck in the boot loading spinner, and that is it. I try doing many things, than resorted to reinstall the vm. That fixed it... For few days, than I got the same problem. After I remove the sound card passthrough from the vm config, all works well (except I do not have audio). Turning it back on, breaks the booting again. I kind of think there is something wrong on driver level, and that some of the windows updates breaks it, but no idea how I can verify. Dose anyone have suggestions?

RiDDiX Posted March 22, 2022 Share Posted March 22, 2022 Hey, always try this by adding this line in to your xml where <features> is located: <features> <acpi/> <apic/> <hyperv> <relaxed state='on'/> <vapic state='on'/> <spinlocks state='on' retries='8191'/> <vendor_id state='on' value='1234567890ab'/> </hyperv> <kvm> <hidden state='on'/> </kvm> <vmport state='off'/> <ioapic driver='kvm'/> </features> This mostly fix Error Code 43 and a few more.

nGran Posted March 23, 2022 Share Posted March 23, 2022 (edited) Thanks for the reply. I added this config, but no result. Most of the config was already the same, but i have copy/pasted it to be sure. If you have other suggestions i will appreciate it. Edited March 23, 2022 by nGran Quote Link to comment
RiDDiX Posted March 24, 2022 Share Posted March 24, 2022 Did you have multifunction on with you GPU / Audio Kombo? Or is it a seperate Audio-Card? 1 Quote Link to comment
nGran Posted March 24, 2022 Share Posted March 24, 2022 It is fixed Ok, RiDDiX, asking me about this "multifunction" feature made me look in the VM xml and i noticed that i have 3 items as hostdev (GPU, the audio that is onboard the GPU, and one USB controller, that i pass to the VM for mouse and keyboard). While trying to understand how dose the "multifunction" work, i just removed the USB controller, and windows booted. Returning the USB, broke the boot again. So as i can see it, there something that was breaking between the USB controller and the GPU sound card. So i decided to test with some settings. I changed the "USB Controller" from "2.0 EHCI" to "3.0 (qemu XHCI)" and all worked. No idea why the problem was not showing after fresh install of windows, but at least now it works.
