The C xenstored has no mechanism for remembering the list of registered watches over a restart. Things like the backend drivers in dom0 rely on watches which are registered at start of day (with no way to reregister) so if you restart xenstored then they stop working and you can't start domains etc. > I used to do the same with the > setting and it used to work fine. Are you sure? I don't think this has ever worked. It might be possible to restart the ocaml xenstored, if you arrange to give it the appropriate command line parameters. Ian.
