Help to passthrought my iGPU Intel i7 11800H

[Anodin67]

Hello,
I am trying to passthrough my Intel igpu on my proxmoto my linux vm. I modified the grub + modprobes targeting my igpu (I followed this tutorial) but it doesn't work, among the list of PCI it is not available in midicated.
Also when I do an lspci I see 00:02.0 VGA Compatible Controller: Intel Corporation Device 9a60 (rev 01) when I should see at least Intel Corporation UHD Graphics 620 or something like that. Any help please ?

Edit :
I added my iGPU device to my vm
Before adding :

user1@portainer:~$ ls /dev/dri/
by-path  card0

After :

user1@portainer:~$ ls /dev/dri/
by-path  card0  card1  renderD128

Do you think this will work?

If I'm correct, your processor is 11th Gen. That being the case, GVT-g is not supported and to passthrough you need to use SR-IOV. I'm running a 12th Gen CPU and used the DKMS setup as explained here. Works great and passing through to Windows 11, Plex HW decoding & Linux Desktop with HW acceleration.

Also, to update the entries in the table, run update-pciids
