We want this only for tcp, so we don't set it for other uris. We need it to know what port is migration running. Reviewed-by: Dr. David Alan Gilbert Signed-off-by: Juan Quintela -- This used to be uri parameter, but it has so many troubles to reproduce that it don't just make sense. This used to be a port parameter. I was asked to move to SocketAddress, done. I also merged the setting of the migration tcp port in this one because now I need to free the address, and this makes it easier. This used to be x-socket-address with a single direction, now it is a list of addresses. Move SocketAddress_to_str here. I used to try to generalize the one in chardev/char-socket.c, but it is not worth it. Free string (eric) Handle VSOCK address nicely (not that migration can use them yet).
