Should be easy to fix on the firmware side. TDX has the same requirement and the code is already there, so this should be a one-liner in OvmfPkg/IncompatiblePciDeviceSupportDxe Independent from that we might consider switching virtio to pxe-virtio.rom (i.e. bios-only instead of bios+uefi) for everyone because the uefi firmware comes with a virtio-net driver included. take care, Gerd
