Tried this on my Odroid H2 running Proxmox 6.1-8 but it does not seem to be working.
Right after booting my VM I see Linux Mint logo but soon after that screen goes black and dmesg fills up with following error:
Code:
[  995.296995] DMAR: DRHD: handling fault status reg 3
[  995.297003] DMAR: [DMA Read] Request device [00:02.0] fault addr 7c90a000 [fault reason 06] PTE Read access is not set
Any ideas where to look next?

What’s your configuration? Are you passing through the entire host GPU to a single VM or have you tried the gvt-g (mediated devices) method (if indeed this is available for Gemini Lake - It works on my Coffee Lake headless VMs)

I'm passing entire host GPU (haven't tried gvt-g yet) to a single VM and I have exact same configuration as Steffenprox except VM is a bit different. And it's a bit confusing as it seems to work right after VM is started but then suddenly those errors start to come.

Code:
bootdisk: sata0
cores: 4
hostpci0: 00:02,pcie=1,x-vga=1
ide2: local:iso/linuxmint-19.3-cinnamon-64bit.iso,media=cdrom
machine: q35
memory: 1024
name: Test
net0: virtio=BA:39:C3:A8:89:67,bridge=vmbr0,firewall=1
numa: 0
ostype: l26
sata0: local-lvm:vm-100-disk-0,size=16G
scsihw: virtio-scsi-pci
smbios1: uuid=e3b779fb-5724-40b7-8317-bd9c7a05be09
sockets: 1
vga: none

I had try to run Linux Mint also but it did not work. Not every Distro is possible to get work. You can try to install the distro with:

hostpci0: 00:02.0
vga: std
and after installation remove:

Just FYI - I manged to get this working using VM with OVMF (UEFI) BIOS setting. Tested with Ubuntu and Debian. Ubuntu worked out of the box but Debian needed to be installed before without adding PCI GPU and after installtion was done PCI attaching enabled passtrought.

Hello, may you give more information because applying the parameters decribed before do not give me a satisfactory result.
In my case, Ubuntu or Debian are running, HDMI with sound is working BUT the GPU (Intel HD Graphics) is not recognized (still seen as a "llvmpipe" card in Ubuntu or in Kodi). What is your GPU ? Do your guest perfectly recognize your GPU ? Hardware acceleration works ?
Thank you for your help. Bye.
