You might see this from programs like virt-cat if you try to run them on something which is just a disk image, not a virtual machine disk image. +=head2 What do these C<debug*> and C<internal-*> functions do? + +There are some functions which are used for debugging and +internal purposes which are I<not> part of the stable API. + +The C<debug*> (or C<guestfs_debug*>) functions, primarily +L<guestfs(3)/guestfs_debug> and a handful of others, are used for +debugging libguestfs. Although they are not part of the stable API +and thus may change or be removed at any time, some programs may want +to call these while waiting for features to be added to libguestfs. + +The C<internal-*> (or C<guestfs_internal_*>) functions are purely to +be used by libguestfs itself. There is no reason for programs to call +them, and programs should not try to use them.
