Yes, setting the hostname, root password and NIC info is possible in
3.3, using cloud-init and the Java SDK. I tested this with 3.3 and it
works correctly.
As you are having problems I suggest to try it manually, from the GUI,
if it doesn't work then please report the details, so that we can
diagnose and fix it.
Once it works manually from the GUI, we can see why it doesn't work with
the SDK, but we will need the output generated when running in debug mode.
