[Openstack] [neutron] Connection to neutron failed: Maximum attempts reached

Can you check that neutron server is actually running?
It should create a listening tcp socket on the port 9696.
Can you also look at Neutron server logs? If there is some misconfiguration
and Neutron server fails to start, logs could give a hint about what is
wrong.

Thanks,
Eugene.
