Ah, no, it's not unique... It's just the host IP address and the same port as the multicast address, so it'll be the same for all qemus on the same host. I've checked how Linux bounces the datagram, it's through the loopback interface, and thus dispatched over all listeners without distinction. I don't see any way to get the information that the packet comes from us, except using the ethernet content. Samuel
