I have installed PVE 8.1.3 on a Lenovo ThinkCentre M700 with Core I3 6100 (Skylake, Intel HD Graphics 530) and an H110 motherboard. After some experimentation and banging-of-head-against-wall (including having to use a custom EFI shell to modify the BIOS setting for VT-d, which Lenovo decided we don't need a menu item for in the BIOS settings screen, but thanks to a helpful Reddit user I finally found out how to fix), I finally got PCI passthrough working on it. Unfortunately, I don't have any output on the VGA, and my guest system (Windows 10) thinks the display has a non-plug-n-play monitor attached, which is wrong.
I've read the documentation about this here, but am not sure I entirely understand it. Specifically, I'm not sure what the deal with "fw_conf" is, or how I'd do what it's talking about...
I've tried a few different combinations of settings in my .conf file. I started with the following settings:
I've experimented with using SeaBIOS and q35, but neither seemed to help. I've tried the following different settings for the PCI passthrough (all at different times, obviously, not in combination!!):
(gpu-hd530.rom is a ROM extracted from my device following the instructions here, while i915ovmf.rom is a custom OVMF with support for Intel HD Graphics, found here)
My kernel command line is
(I've also tried enable_gvt=1 and without the enable_guc section). My IOMMU groups look fine (the GPU is in a group by itself), so I took the ACS override out (but I did have it earlier during my experimentation). The i915 module is blacklisted (along with sound modules, although I haven't even tried to pass those through yet). My various module options are:
The modules I've got set to preload in /etc/modules are:
Can anyone suggest anything I've missed? I'd really rather not have to spend extra cash on yet more hardware,,,
