Is it possible, and how, to forward a port from guest to host in qemu/kvm?
Note do I mean (out of) from guest to host, and not from host into guest (that's widely documented).
I think I'm looking for the "opposite" of hostfwd/redir.. Like I use & understand -net user,hostfwd=tcp::8022-:22
which connects port 8022 on the HOST to the GUEST - great. Now I also want the "opposite", and need to get connections made to port 6633 in the GUEST out to the HOST, where some process is running waiting for connections on that.
Is that easily possible with some --option I cannot find, or is that a stupid request betraying my lack of networking understanding - like that's not possible like that?
