thanks for your reply, When I set the debug mode and run "libguestfs-test-tool" the result is: [...] libguestfs: launch: version=1.24.5
I'll assume this is an old Ubuntu version, in which case you need to run: sudo update-guestfs-appliance See: http://libguestfs.org/guestfs-faq.1.html#libguestfs:-error:-cannot-find-any-... This is not required in newer versions of libguestfs.
