How were you able to achieve making it work, are you using lastest proxmox version, and latests intel graphics driver, or any other version?

[GUIDE] Intel Intergrated graphic Passthrough
- Thread starter luxflow
- Start date
Kind regards
hi, i tried follow this guide to pass through my HD2500 graphic on my b75 motherboard ,after configuration the windows seems detect IGPU but if I try to install driver for it , I got a blue screen with this error “system_thread_exception_not_handled (igdkmd64.sys)”
So i had a completly working Windows VM with a VertIO GPU. I decided I wanted to pass thru the IGPU (i have a xeon E3-1260L Sandy Bridge)... I have looked at 100 different setups and configs... everything i do ends in the same result.
grub:
I know someone else got turned away for this code... but its obviously hooked to the vfio pass thru. I can confirm that the gpu is in its own Iommu group...
IOMMU:
lscpi:
It also shows that the igpu is running under vfio driver, and there is no output (So i assume proxmox is no longer loading it). I tried this setup with this same result... I tried setting "hostpci0: 00:02.0,legacy-igd=1" in the VM... I've googled and looked and tried just about everything and cant figure this out. The only thing I found was a write up on qemu's page about memory allocation and setting this below 4G... but I tried add these lines to the VM which was supposed to fix that: "args: -device vfio-pci,host=00:02.0,addr=0x02,x-igd-opregion=on,x-igd-gms=1". I even pulled a bios image and got the rom file for the igpu and tried loading that... same message.
Nothing changes the message... I'm at the end of my talent and hoping someone knows what to modify to make the memory issue go away...

Hello,
Finally, i get to have the Integrated Intel GPU of my Haswell i5 4250u (HD5000) to work in passthrough mode with a recent proxmox 6.4.4/
First i want to thanks sshaikh for this post. I didn't known it was possible to change code and i had to do it off course !
https://forum.proxmox.com/threads/igd-passthrough-and-hard-coded-pci-bridges.68285/
https://www.reddit.com/r/VFIO/comments/fx4pa0/haswell_igd_passthrough/
First, as Haswell is too old, i read i had to forget UPT mode, and go for legacy. I guess this means it is impossible to use q35 machine, whereas everybosy say , use q35 ! i tried many setups with q35, nothing on HDMI. My next Hystou will be UPT !!!
Well, it works, but i'm limited in resolution at 1024x768 and a few colours ( such as the good old beginng of computers !)
Actually, i have the "basic W10 video drivers".
I wonder if someone has an idea to get the Intel HD 5000 drivers to be installed...
Thank you.
Here's all i've done :
The ultimate trick ! :

I just want to passthrough my HD Graphics 530 into windows.
After installation of windows the driver is installed correctly without error.
But as soon as I start the machine the display of my monitor goes black for a short time and then it says no signal.
Does anyone have a hint for me?
Tried many solutions with "-args..." but nothing helps.

Has anyone managed to get iGPU passthru to work on a 2012 Mac mini?
I'm trying to pass through to MacOS Monterey VMs.
I have gotten as far as getting the iGPU to show up on the list of Graphics/Displays ... Apple | About This Mac | System Report | Graphics/Displays ... will show a list of two. The first item is "Display" which shows 7MB VRAM and the second is "Intel HD Graphics 4000" which has no VRAM.
But in opening the Activity Monitor, there is absolutely no GPU activity, even in apps that would/could utilize it.

Hi. My Proxmox 7.3-6 run on a Fujitsu s761 Laptop (Sandy Bridge 2nd Generation Intel).
With iGPU Passtrough Win11 VM run only with this settings:
The VM starts with OK but my problem is that the laptop screen goes black when the VM starts. Is there a parameter that tells me to use the internal panel?

Now I'm one step further with the following I see the Windows Installer loading bar on the Laptop Panel:

But then is the screen black. I see the screen is on.

This is because the VNC console doesn't work when you passthrough the GPU, so you need to enable RDP to access it. Also make sure that display is set to NONE.
Hello,
I had the good idea to upgrade PVE too, to 7.4 precisely. I spent hours try new parameters and intermediate kernels, believing that new kernel was producing a regression. Finally, i had discover that /usr/share/perl5/PVE/QemuServer.pm was simply overwriten during upgrade. Actually, i lost the pve server, and had to reinstall proxmox, but never thought that the file returned to its original behaviour.
So, good news, the trick for Haswell still works ( see previous post ), you just need to change the file again (one line).
Btw, it seems pve takes more memory, so try to adjust max memory of vm to a level below, else, OOM pop after a while of running windows. For the total of 8 Gb, i had to lower 200 Mb the windows vm.
It is very frustating to loose the PT on upgrade, but, as it was a direct change of python file, that could happen, that's the point.
Well, i don't know why this brige is force when machinen is not q35 , and we can't use q35 because haswell is not UPT, but i guess this will never be fixed as the concerned processors are old.
Hope this will help.
I have an Asrock Z87 Extreme4 with a Core i5-4690K // HD Graphics 4600 and I'm running Proxmox 8.2. I've managed to passthrough the iGPU in a Windows 10 x64 using SeaBIOS (sound not working though) but I have a few questions that I would like to clarify. Let me share what I did first:
These are my questions:
- How do I make my HDMI audio work?
- My VM seems to be freezing at boot if I set the Display option to none (vga: none in config file). Why? I tried to access it through remote desktop but it does not go through.
- I've tried the OVMF (UEFI) route but it didn't work for me. I just could not get rid of the infamous 43 error code. My settings were the same as the ones I've shared here, except for the VM config, which had this instead:
I have tried booting it with the Display Option in none and the machine booted without issues but the 43 error did not go away.
- When it comes to Linux and macOS guests, the configuration is the same or are there specific configurations for those operating systems?
----------
EDIT
Regarding the audio, I did the following to at least get audio from the audio jack and it worked:
- I added the High Definition Audio Controller (00:1b.0):
vfio.conf
VM Config file arguments
Now I can see 2 audio devices in my Device manager but I still get no sound through my HDMI:

I am currently making a VM with Windows 11 IoT Enterprise LTSC using SeaBIOS to try this on my HD 620. I am wondering what machine type you used?
