I am running into a problem where I am trying to pass the Intel IGD to any virtual machine (Windows, macOS, Ubuntu) , but vfio runs into FLR problems where the IGPU appears unresponsive. As of right now, I've tried to make it work on Proxmox VE 7.0, 7.1 and 7.2, but to no avail.
I am running Proxmox on:
- z590 chipset
- i7 10700 (comet lake)
The GRUB_CMDLINE_LINUX_DEFAULT is as follows:
I got the vfio.conf set up with the correct address of the IGPU.
lspci -knn indicates that vfio-pci has correctly taken over the device.
However, I get an error (0000:00:02.0 is the IGPU):
I found a Reddit issue, also linked to a post on this forum, which conversed on the same topic, but I found it unhelpful as I am not proficient in compiling kernels and whatnot. How should I fix this error?
