It seems that unmap will be done at the end of xc_dom_boot_image (see xc_dom_unmap_all). The latter function will go through the list of all mappings and close it one by one. You can add a print in xc_dom_unmap_one (tools/libxc/xc_dom_core.c) and check if you have the same number of print with xc_dom_pfn_to_ptr_retcount.
