Hi to all.

I've got a server proxmox 3.2 with pvetest repo with fully working passthrough to various vm.

Due to most recent patches, my machine runs on kernel 3.16.2 with some patches (intel arbiter)

I'm trying to create an openelec VM and thus I need intel igpu passthrough(latest vga available in my system)

When I start the vm I get :

dmesg
Code: 
Device is ineligible for IOMMU domain attach due to platform RMRR requirement.

Tried to passthrough also intel hd audio device but /dev/vfio/14 that refers to 02:00.0 is busy.

Is there a mode to disable completely intel on proxmox. I'm currently using server only by SSH/web interface and I don't need proxmox gui on monitor connected to motherboard...
