Hi Domenico --
Do a standard server installation.
Run the command "VirtualServiceEnvironment --help"
One of the command line arguments is "-m" for the Registry connection. There are other command line options you might want, such as -n for naming your VSE.
So, run this:
VirtualServiceEnvironment -m tcp://registryServerHostName:2010/Registry -n uniqueNameForThisVSE
This will connect the VSE to the specified registry instance.
When it connects, DEVTEST_HOME/site.properties will be overwritten with the file of the same name from the Registry machine. In this way, it's using the same database configuration.
When you're happy with how it connects, make a batch / shell script to run the whole command line. If you're interested in making run as a Windows service, you'll need to find that service launcher in your Windows configuration and add the command line options.
