Intel NUC Integrated Graphics passthrough on 6.2-4

[Preference]

Hi,

Making my own thread as I desperately need this to work in order to go all in on Proxmox. Seems like there might be an issue with the latest version (6.2-4) preventing passthrough from working, but I haven't seen it confirmed: https://forum.proxmox.com/threads/passhtrough-8gen-intel-nuc.53750/page-2

I have this NUC https://ark.intel.com/content/www/us/en/ark/products/126150/intel-nuc-kit-nuc8i3beh.html with Intel® Iris® Plus Graphics 655

I don't care much which OS i get it working with, but I am currently trying with Ubuntu. Happy to post any relevant files or logs and appreciate any help I can get Have been trying settings and options from many threads, but mostly the previous linked one and https://forum.proxmox.com/threads/guide-intel-intergrated-graphic-passthrough.30451/

Spoiler: /etc/modprobe.d/blacklist.conf

blacklist snd_hda_intel
blacklist snd_hda_codec_hdmi
blacklist i915

As far as I have understood the blacklist is there to disable the GPU for the host (Proxmox), but even with these settings the display does output Proxmox data (as far as I know, as it displays the same when all VMs are off). This is what is displayed on the attached monitor:

Loading Linux 5.4.31-1-pve ...
Loading initial ramdisk ...

Make sure you're system is booting in UEFI mode, then even the "Loading XXX" shouldn't be an issue. Do you actually get an error when you try to pass the device through? Could you provide some logs, error messages, descriptions of the issue, etc...?

Also, check out this thread, where a new feature related to Intel iGPU passthrough ("legacy-igd") is discussed (you can enable it by editing your /etc/pve/<vmid>.conf and appending ",legacy-igd=1" to your "hostpci" device).

Thanks Stefan for the quick response. When I tried again to be able to provide you with some logs I setup a new VM and what do you know, the Ubuntu logo appeared on the screen instantly! Now is there a way to use both the external monitor and a console like the noVNC one in Proxmox?

Not via PVE, but you can of course just set up a VNC (or x2go or whatever) server within the VM and use that.

Thanks, not a critical need for it, but would have been easy if it was possible in PVE. The important part is in order and I can finally start building up my services again using Proxmox Very excited!

For anyone having similar issues and checking this thread - try to setup a new VM after applying all the changes to the Proxmox config files
