I have the following device: Thinkpad P50, i7-6820HQ + HD530 and Quadro M2000M(GM107GLM), which I'm trying to assign to VM(Windows 7 at the moment). I followed several guides on the Internet, primary the one at Arch Wiki. My problem is that I can not install drivers in Windows. NVIDIA driver says that it can't find compatible device and Windows Device Manager shows GPU as "Standard VGA Graphics Device" and doesn't allow to install driver manually(says driver is incompatible with current windows version). I tried version 375.63 downloaded from NVIDIA web site. I did not check does NVIDIA output something on external monitor or not because I don't have external display at the moment of writing. I will probably do it as soon as I get access to it. NVIDIA GPU seems to be wired to HDMI/Display Port, while IGD rules internal LCD screen. I did not manage to keep both cards working and get picture on LCD rendered by NVGPU, so I guess NVGPU renders image and then passed it to IGD which displays it on laptop screen. I wonder though, how does it work when only NVIDIA GPU is enabled in BIOS. Here is details of my setup and logs(I use ARCH, kernel version is 4.8.4-1-vfio): 1. CPU supports VT-d/Vt-x and IOMMU is turned on in kernel parameters trough GRUB. Also ACS patch applied(with pcie_acs_override=downstream) $ dmesg|grep -e DMAR -e IOMMU [ 0.000000] Warning: PCIe ACS overrides enabled; This may allow non-IOMMU protected peer-to-peer DMA [ 0.000000] ACPI: DMAR 0x0000000057FFD000 0000A8 (v01 LENOVO TP-N1E 00001300 PTEC 00000002) [ 0.000000] DMAR: IOMMU enabled [ 0.067448] DMAR: Host address width 39 [ 0.067449] DMAR: DRHD base: 0x000000fed90000 flags: 0x0 [ 0.067453] DMAR: dmar0: reg_base_addr fed90000 ver 1:0 cap 1c0000c40660462 ecap 7e3ff0505e [ 0.067454] DMAR: DRHD base: 0x000000fed91000 flags: 0x1 [ 0.067457] DMAR: dmar1: reg_base_addr fed91000 ver 1:0 cap d2008c40660462 ecap f050da [ 0.067458] DMAR: RMRR base: 0x00000057eaa000 end: 0x00000057ec9fff [ 0.067458] DMAR: RMRR base: 0x0000005a000000 end: 0x0000005e7fffff [ 0.067460] DMAR-IR: IOAPIC id 2 under DRHD base 0xfed91000 IOMMU 1 [ 0.067460] DMAR-IR: HPET id 0 under DRHD base 0xfed91000 [ 0.067461] DMAR-IR: x2apic is disabled because BIOS sets x2apic opt out bit.

I use GPU ROM file, which I got using the followng guide: https://lists.freedesktop.org/archives/nouveau/2011-October/009368.html I get exactly the same error code as given as example in the message by link above, and used ACPI to retrive ROM. ROM file is attached here: https://anse.me/owncloud/index.php/s/DWBLpxVNz4tfGE1 6. Finally, my VM config.
