When I register a callback for events with this function call:

"libguestfs: error: lstat: /.Trash: No such file or directory"
I still get them in stderr ..
Thanks,
Or

(3) Call guestfs_parse_environment to parse the environment. This
would have been done by guestfs_create, except you set the
NO_ENVIRONMENT flag.
if (guestfs_parse_environment (g) == -1) {
/* see below ... */
(4) For guestfs_parse_environment and all other libguestfs calls, you
should check the return codes, and handle erro...
