Windows has stopped this device because it has reported problems. (Code 43)

sadly did not work for me, on PVE 8.2.2 I had passthrough partially working even without these steps, but it was very unstable. these steps worked once, caused the host to crash then never worked again. I'e not been able to get pci passthrough to work properly on ESXi either. it's an old Supermicro AMD Opteron systemm and does have IOMMU but it seems to be very unstable.

i have an amd 7840HS with iGpu Radeon 780M what if the correct GRUB_CMDLINE_LINUX_DEFAULT for this cpu/igpu ? amd_iommu=on i know, but what i need is for this (eg: intel_iommu=on i915.enable_gvt=1) ? thanks 4 help

i have Intel N97 CPU, should I remove i915.enable_gvt=1 parameter?

Are you able to connect an HDMI cable to your motherboard using this guide and use a display directly from your motherboard from a Windows VM?

fastest and simplest way 10 out of 10 points guide thank you very much

vfio-pci 0000:00:02.0: Invalid PCI ROM header signature: expecting 0xaa55, got 0xffff

but it's for split one i want full passthrough is there anything??

Is step 1 & 2 really still necessary for just passing through the GPU to a VM?

Using arc and it all works except inside of windows Im getting an error 43 from the gpu.

did anyone had luck with n100 igpu? no matter what i do, its always error 43 in windows drivers

where you get gpu number 2:24 ?

what about amd igpus? Any guide for 780m?

how can I add the GPU for Synology DSM 7.2?

Do you have this as a text file so that I don't have to go back and forth with the video?

Amazing, exact same iGPU worked flawlessly thanks alot!

need guide to do iGPU for Ryzen instead of Intel any chances?

Will this work for proxmox ve 8.2.2

can you help me please? root@proxmox:~# update-initramfs -u update-initramfs: Generating /boot/initrd.img-6.8.4-3-pve Running hook script 'zz-proxmox-boot'.. Re-executing '/etc/kernel/postinst.d/zz-proxmox-boot' in new private mount namespace.. No /etc/kernel/proxmox-boot-uuids found, skipping ESP sync. System booted in EFI-mode but 'grub-efi-amd64' meta-package not installed! Install 'grub-efi-amd64' to get updates. Couldn't find EFI system partition. It is recommended to mount it to /boot or /efi. Alternatively, use --esp-path= to specify path to mount point

I must thank you. This is the only guide that I've used that worked for me. Thanks again.

For AMD motherboards: change "intel_iommu" to "amd_iommu"

this was helpful, thank you!

how about gpu for laptop?

❤

Best tutorial I've ever seen, thank you.

Great! Thanks, this broke my VM it wont start anymore...

It didnt worked to me... i had followed all the steps only missing that my VM is Windows 10, not 11. I have a NVIDIA Tesla K20XM, can someone please help me?

for ryzen 5700U dont work

can 2 vm access the same gpu at same time ?

Ubuntu vm can output to monitor but win 11 can not.

I did this with my pentium G4560. The GVT-G or split passthrough works well but I cannot do any full igpu passthrough sadly.

What about outputting video over hdmi? My screen stays off when I boot the vm.

With 720p resolution

kvm: -device vfio-pci,host=0000:11:00.0,id=hostpci0.0,bus=ich9-pcie-port-1,addr=0x0.0,x-vga=on,multifunction=on: vfio 0000:11:00.0: failed getting region info for VGA region index 8: Invalid argument device does not support requested feature x-vga TASK ERROR: start failed: QEMU exited with code 1 I get this error when I run the virtual machine

Wich CPU was tested? Does this work with Jasper Lake ?

Great Video! How would the VM setting need to look if I'm running a Ubuntu VM?

Thank you for the best step by step tutorial of this feature! I appreciate it........grin

Hello again, also I think you didnt include the audio for igpu is due to the IOmmu conflict with the network device (this possibly would make your video very long.). I bypassed this by getting a usb3 ethernet dongle (tp=-ink) and unplugged the network device so its not being used. Add the Pcie audio device with functions and Rom unchecked and you have audio in your Windows. Linux you follow the same info in the video. Also use Seabios and i440 for Windows. Not sure how you used OVMF and Q35 but good job. Good luck!

AMD?

Excellent video. I would be really interested to see this working with a linux desktop VM?

Execellent video... thank you for this video.

This is for amd or intel?

Can i use an Intel ARC 750 GPU?

First actually good AI tutorial, thank u

i did it tks you

Hello, when I add the PCI, I can't start the VM, and I have this error : kvm: -device vfio-pci,host=0000:21:00.1,id=hostpci0.1,bus=ich9-pcie-port-1,addr=0x0.1: vfio 0000:21:00.1: failed to setup container for group 20: Failed to set iommu for container: Operation not permitted

Can you pas through igpu to windows vm and attach a real monitor? I have i5-8400 cpu.

I followed the instructions, however i got an error when trying to use primary GPU. I had to turn it off to boot the Windows VM. I will say its now working perfectly. Thanks you. I too had a rx580 as my card.

Hello... when VM is turned off, does the GPU still takes some power? Asking because I have a homelab machine that runs 24x7... I am thinking to install a GPU (RTX 3060) on it and passthrough to a windows 11 VM for occasional gaming.... my only concern is, since my homelab machine is on 24x7 where as Windows VM (for gaming) will only be turned on few hours a week.... when the VM is off, is my homelab machine still using gpu power? or is it possible to completely turn off the gpu when windows vm is off/suspended
