GPU Passthrough not working

Hey community,

For a while now I've been trying to passthrough a Nvidia Quadro M2000 to a VM, unfortunately without any luck so far.

As starters I read through the PCI Passthrough wiki and followed the steps, but when I try to start the VM I get the following error:
kvm: -device vfio-pci,host=07:00.0,id=hostpci0.0,bus=ich9-pcie-port-1,addr=0x0.0,multifunction=on: vfio 0000:07:00.0: failed to setup container for group 23: Failed to set iommu for container: Operation not permitted

Looking at dmesg, I see the following:

I've been searching for a solution, but haven't found any so far. Is there someone that can help me towards a solution? I've the configuration files as spoilers at the bottom of this message.

this is a motherboard issue, i guess it is a hp machine? it might be fixable with a bios upgrade and also there was some thread (cannot seem to find it right now) where there was a possible fix

but in general this is a limitation out of reach for proxmox
