I think this is not a bug, but you are using the command line parameters
in a wrong way. When you use "-net user,hostfwd=tcp:127.0.0.1:1122-:22"
you are creating a *new*, second host network device which is not
connected to the guest NIC device that you specified. Please try to
avoid mixing "-net" and "-netdev" options. You should rather do
something like this instead:
-netdev user,id=unet,hostfwd=tcp:127.0.0.1:1122-:22 -device virtio-net-
device,netdev=unet
