[Giuseppe Calarco]

Hi,
I have a problem when i run java examples of libguestfs. It needs root
privileges. This is the output of libguestfs-test-tool:

See earlier debug messages.
Or you can run 'libguestfs-test-tool' and post the complete output into
a bug report or message to the libguestfs mailing list.

I hope that help me. Thanks in advance.
