You have two nics in the command line. Anyway using a proper split
-netdev/-device specification:

  -netdev user,id=unet,hostfwd=tcp::2222-:22 -device virtio-net-pci,netdev=unet

which in this case forwards tcp port 2222 on the host to port 22 on the
guest. Just don't expect brilliant performance.
