I don't think this kind of information that relates to libxl internal belongs here. Anyway, to answer you question. libxl_retrieve_domain_configuration is called by xl when you do migration / detailed domain configuration listing etc. I think the comment above MERGE macro states what it does and how to use it. Is there anything that's not clear to you? Wei. _______________________________________________ Xen-devel mailing list [email protected] http://lists.xen.org/xen-devel
