As I mentioned on edk2-discuss, I'd suggest two tweaks (independently of each other): * try the builting virtio-net driver rather than the iPXE one. For that, use: -device virtio-net-pci,[other properties],romfile="" that is, add a 'romfile=""' property * Try using a different -netdev backend than a UDP socket.
