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.
libguestfs lets you edit virtual machines. Supports shell scripting,
bindings from many languages. http://libguestfs.org
