It might be something obvious but I couldn't see what was wrong. (NB: The socket passed in is *connected* already).I'm looking into this (right now just for something obvious, if nothing pops up, a bit later) but actually I wonder: couldn't qemu() from 5/5 just call socket(AF_UNIX, SOCK_STREAM, 0) and connect() on it? Or am I missing something? Then sure, as you mentioned, this could be useful for something else, so it's probably worth it to get it working. -- Stefano
