Your code has to wait until the cloning has completed. The IProgress
object isn't returned for fun, it serves an important purpose. Without
it there's no good way to tell when the cloning has finished. It can
take a very long time, as your code creates a full clone which
potentially means copying many GBytes of virtual disk contents. Only at
the end of the VM cloning the settings are all in place...
The best "sample" is always the source of VBoxManage - it's C++, but the
API works in principle the same in all languages, with minor differences
in the error handling and thus details of the parameter list.
