Sadly, the forward mode opens only one connection when the machine boots. Therefore, if you want to forward every new connection, you will have to go through netcat or a similar program. For example, I used this option to redirect connections to 10.0.2.100 to an HTTP server I created with Python: -nic 'user,model=virtio-net-pci,restrict=yes,guestfwd=tcp:10.0.2.100:80-cmd:netcat 127.0.0.1 8000' And that was enough for me to pass a few files without using Samba or swapping isos.
