Hi Karl,

We have looked at the Java refactoring work. I seems most of that work was =

We could not find any posted changes to the systemvm's, unless we are looki=

Daan asked me to drop you a mail and explain a little bit where we have bee=
n concentrating our efforts.

Most of the Java refactor is indeed what you saw, a refactor to make the co=
de more logical, eliminate duplication get the methods better aligned with =
the classes and so on but that is not all.

We have also introduced a new way of sending the configuration to the syste=
mvm itself.  Instead of calling scripts, a json file is passed to the serve=
r and processed.

The processing is done by some python code (to be found in /opt/cloud/bin)

The idea is that it is a self healing convergence based system.  We had pla=
nned to use chef solo to do this but, it was just too slow.

If you spin up our branch and make your self a network and an instance, log=
 on to the VR and take a look in /etc/cloudstack and /var/cache/cloud/proce=
ssed

It would be really interesting to use to maybe share ideas and work.  It wo=
uld be such a shame if we are duplicating each other=92s efforts!
