Not exactly, as I currently don't have a second GPU I could install in the machine (yes, really). I guess that may be a problem, although I can confirm that I have disabled the GPU for use outside the VM alltogether. I will see if I can come up with a second GPU for testing purposes.

dmesg output (the same as before): root@proxmox001:~# dmesg | grep -i vfio [ 4.741904] VFIO - User Level meta-driver version: 0.3 [ 4.749689] vfio-pci 0000:01:00.0: vgaarb: changed VGA decodes: olddecodes=io+mem,decodes=none:owns=io+mem [ 4.766409] vfio_pci: add...

Hi, thanks for the suggestion. I dumped the rom file exactly as described, and GOPupd it, also as described. However, the VM fails to even POST when using the resulting ROM, is there a way to find out what happended, are there any logs? regards

I tried it with a "normal" Windows 10 Pro, however, I could not get it to work. I am out of ideas, especially since I think that hostwise everything is working correctly, and I do not know what I could change in the windows guest.

I am using the following driver: 471.68-quadro-rtx-desktop-notebook-win10-win11-64bit-international-whql I didn't try it on a bare metal machine yet (not that much spare parts around...) But I tried it on a ubuntu vm... and things are looking better? est@test-Standard-PC-Q35-ICH9-2009:~$ sudo...

Hi, I am able to boot the VM and connect via RDP, however, still Code 43. The last output of dmesg is: root@proxmox001:~# dmesg | grep -i vfio [ 4.741904] VFIO - User Level meta-driver version: 0.3 [ 4.749689] vfio-pci 0000:01:00.0: vgaarb: changed VGA decodes...

Tried it, unfortunately nothing changed. (BSOD as soon as I turn on "primary GPU" for the VM). I have to stop for today, but I will try again in a few days. Maybe I will try it with a clean and fresh install... In the meantime, thanks for all the valuable input!

Is the output of my rom-parser tool maybe the confirmation that my GPUs vbios is broken? I found a bios on techpowerup, but it's not verified, though all the specs map. I'm willing to risk it (its only for testing purposes anyway). Just so that I get that correctly: Do I have to flash the...

Hi Stefan, Thanks for the quick response! I will remove the fullflush command and just use iommu=pt. Maybe the wiki needs an update, because it also mentions to use amd_iommu=on. This is the output of dmesg grep iommu: root@proxmox001:~# dmesg | grep iommu [ 0.000000] Command line...

Hi, I know there are a lot of posts about (not working) PCie passthrough, and I am pretty sure I have read all of them. However, I do not seem to get it to work on my Quadro P400. System spec: Asus Crosshair V Formula AMD FX-8350 Quadro P400 16 GB Ram Standard SATA SSDs The Quadro is the...
