Right. It's not trivial to change the xtl API because there is no negotiation, just a vops structure. I can think of a way to do it, but do we want to make all xtl logger users (that is, all generators of log messages) pass a domid ? Do we want to extend this to other information ? (Not sure _what_ other information.) Alternatively, we could have libxl (and perhaps libxc) put the domid in a standard format in the message, so it could be extracted ? However we do it, we would have to add a domid to every LOG call in libxl.
