Hi Ciro, This doesn't work straightforwardly right now. For gdb, I believe there is a special case for debugging the guest application (see remote_gdb code).
Otherwise, there is a special network device: "EtherTap" that allows gem5 to send network request to the host. See src/dev/net/Ethernet.py. EtherTap is very hard to get working, though. I've had mixed results.
