Well its been a long time since I have coded anything in c and time is a factor (as I just don't have any to spare). I'll have to figure something else out for it. The modifications would be more than net/socket.c, as the client connects to the tcp server/listener and when it goes away, there is

Stefan, I just tested the most recent version of qemu (1.4). I have 2 virtual images back to back via a tcp socket. They can ping eachother, but when I down the listener and bring it back up (meaning killing the kvm and relaunching) it cannot ping anymore. The connector never retries to connect
