I can't run a cloudpipe instance in diablo using a Vlan because I have
an exception (please look the Trace1 Below).

I debugged the code and I have seen the function "fixed_ip_associate" in
"nova/db/sqlalchemy/api.py"
is called without set "network_id" so I changed the function
"allocate_fixed_ip" in "nova/network/manager.py"
and I passed the missing "network[id]".

...
    def allocate_fixed_ip(self, context, instance_id, network, **kwargs):
        """Gets a fixed ip from the pool."""
        if kwargs.get('vpn', None):
            address = network['vpn_private_address']
            self.db.fixed_ip_associate(context,
                                       address,
                                       instance_id,
                                       network['id'],  <------------ Added
argument
                                       reserved=True)
....


With that change the cloudpipe instance starts but the command  "nova-manage
vpn run project_id user_id"
return another exception (please look the Trace 2 Below).

What is your experience running a cloudpipe instance with Diablo and Vlan?
does it works?

Thank you,
Andrea.
