Hi Steve,

I got it working.. I have been working on a web launcher to start up
components for our test bed at CERN.

As the component grew, so did their configuration description files, and it
became bit tricky to manage various files for various configuration for less
advances user, who are more concerned about getting their grid node running
rather than to deal with Smartfrog itself.

So sometime ago, I made up a web interface for component generation,
http://cern.ch/vgrid/tools/ , which was outputing the configuration for VM
deployment to the browser. But later on I felt it would far more simpler to
deploy a virtual machines, with the created smartfrog component description,
via the web.

So while I was doing it yesterday, somehow I was getting this strange error.
First I thought, perhaps, Python was not able to execute because of
permission restrictions, although it was running under root on SLC4. So
simply extending the rights to the sfConfig file, Python was able to deploy.

So now on, for our test bed, we can deploy virtual machines through a web
interface, with smartfrog as deployment mechanism, with click of the button!
The server's smartfrog client act as  server deamon, and Python server is
also running on the same machine!

Cheers
Omer
