Hey,
I originally wanted to run Kodi on my newly build proxmox device (ASRock B365M-ITX/ac, Intel Core i5-9400, 16GB Crucial DDR4 RAM, 500GB Crucial P5 NVMe SSD) and tried to do it with LibreElec by using some manuals I found during my google search (also from this forum). I couldn't get the iGPU from my Intel CPU and the HDMI output to work.
A user in this thread mentioned he successfully got it to work with a Ubuntu VM (on which he then installed Kodi I think) but also trying to rebuild his setup I could not get it to work. The HDMI output would just display nothing and the Proxmox console would nevertheless stop somewhere after or before the grub screen.
I tried some options (Primary GPU, PCIe, All functions, UEFI/BIOS, Graphics card) but it just didn't work.
Today I looked into the journal log for the first time and could see these lines after I started the ubuntu VM with the passthrough of the iGPU enabled:
Sometimes, there were also lines with fault reason 6 (PTE Read access).
What could the problem causing this be?
I enabled all options related to virtualization in my UEFI (it also says "VT-d supported" in the chipset section).
I enabled iommu through the grub commandline:
And added the PCI device to my VM:
The iGPU is also recognized on the host and the right kernel driver is used:
I did also follow the tutorial of the proxmox wiki here, so the kernel modules are loaded and iommu groups are available:
Can somebody help me with that problem?
Did I miss something?
Greetings,
levin
