Alderlake direct passthrough to Linux VM is working with HDMI output!

[chchia]

Somehow i got the Alderlake passthrough the intel igpu to a linux VM inside proxmox, without any additional works.


Grub only have intel_iommu and pstate disabled.


no need to blacklist intel driver, so i can still have HDMI screen output to my ipkvm until i started the linux host which have the full VGA.


no need to add to vfio-pci, the two listed in the red box is my USB controller and SATA controller.




remote in to the Linux VM using nomachine, works fine.


from ipkvm, can see that HDMI is output the video correctly, perfect!



simple setup in proxmox, just passthrough the whole PCI devices to VM.

i am running on Ubuntu 23.10


i am willing to provide more info if required.

ps: forgot to mention, SRIOV support is disabled in BIOS.

Hi, I'm really struggling on this, like many others.

When I add the RAW pci-e to the VM (Ubuntu 24.04) it simply stops from booting.

Could you please make a tutorial on how did you solve this? I'm sure lots of people will be thankful.

Best regards.

make sure you remove the Proxmox VGA adaptor, any software emulated VGA adaptor will stop VM from booting when you passthrough Hardware VGA.

make sure you have VNC or NoMachine or XRDP installed so you can login.
