If it's ever unclear what libguestfs API calls are being made by guestmount (or other programs) you can set export LIBGUESTFS_TRACE=1 before running the program. See http://libguestfs.org/FAQ.html#debug Specifically for guestmount you can also get a lot more other debug by adding the -x or --trace option.
