I do not have great experience with "Q35 machine type with proper PCIe root complex hierarchy". Selection of the chipset type Q35 in the virt-manager upon creation does not seem to work with UEFI type of firmware (as recommended for vfio passthroug). Or perhaps I should have downloaded a more recent Tianocore UEFI firmware for my virtual machines?
