unable to add rules to security group from horizon dashboard
When I add a security rule to a security group through horizon UI, it is not giving any response.

Can you check the logs to see if the request is going to nova/neutron ?
I have installed devstack. I don't find the nova/neutron log files at /var/log/neutron. I checked syslog file under /var/log/ .I saw some logs for neutron but exactly could not find out logs for adding rules to security group.
Devstack normally has logs under /opt/stack/logs, or more recently (and depending on how you configured it), you use journalctl to see the logs.
