Servers Deployment: Protocol gets executed locally instead

[lenerd]

Hi,

I am trying to get MATRIX to work on a couple of (locally hosted) VMs (again). So, in the configuration I use "servers" in the "CloudProviders" section (see below for the full configuration file).

Hence, in run_protocol in fabfile.py, the variable regions is set to an empty list:

https://github.com/cryptobiu/MATRIX/blob/d27ef034cea26c2003908a2e65ef243abc7e790e/Execution/fabfile.py#L66-L73

As a consequence, MATRIX try to run the protocol on the local machine:

https://github.com/cryptobiu/MATRIX/blob/d27ef034cea26c2003908a2e65ef243abc7e790e/Execution/fabfile.py#L85-L95

So, the servers deployment need to be handled somewhat differently. Maybe, as another case in the first case distinction?

Or do I need to change something in the configuration?

Hi,

I add another option in the fabfile.py for local servers. Your configuration seems fine. Please pull the latest commit.
