interesting project. I think your approach is the right one. What VMController does is (as the name suggests) control VirtualBox. Therefore the Python API is the right interface. It is part of VirtualBox' philosophy to introduce incompatible API changes in major versions. It is therefore to be expected, that you have to perform some adjustments in VMController in order to support VirtualBox 4.0. However, we do not allow such incompatible changes for maintenance updates and we also continue to support and update previous versions of the product.
For each release, the SDK documentation (http://download.virtualbox.org/virtualbox/SDKRef.pdf ) contains a complete list of incompatible API changes with information on how to adjust your code. Check out chapter 12 of the SDK reference.
The extension pack mechanism is indeed similar to the concept offered by Firefox and it's really meant to extend the functionality of VirtualBox. We intent do provide sample code on how to develop extension packs in the near future. However, I don't think it would be the right approach for you.

VMController will be used by BOINC-VM  and LHC++ at HOME , CERN. VMController, uses python bindings of VirtualBox to control the same.

> VMController is broken with the new 4.0 version, if writing extension allows full exposure to VirtualBox interfaces (the same that were provided by the python/java bindings) and a clean deployment/packaging method, I would like to rewrite VMController as a VirtualBox extension/addon. Please let me know about the feasibility of such an extension.
