Good idea, but I think this should be implemented differently so it can tackle
some other problems. Right now the connection selected at startup is just
determined by how the connection key is hashed in a python dictionary, which
is pretty arbitrary.

Can you add a new function vmmManager.set_initial_selection, and call that
from engine.py:get_manager after add-conn/remove-conn signals are registered?
I think the logic should be:

- If URI specified via command line --connect, select it
- else select the first active connection
- else select the first connection

Thanks,
