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.
libguestfs: child_cleanup: 0x9871c80: child process died
libguestfs-test-tool: failed to launch appliance
libguestfs: closing guestfs handle 0x9871c80 (state 0)
I hope that help me. Thanks in advance.
