in /var/log/neutron/neutron-linuxbridge-agent.log

That looks like error on load plugin class file. You should check that the class file exists on on system.

ex) /usr/lib/python2.x/dist-packages/neutron/agent/linux/iptables_firewall.py

Reporting the same issue. This is a standard install following the instructions for CentOS

Neutron use named classes (check the error source is stevedore.named). You have a file setup.cfg that has the correct name for these classes. I think the right value is "iptables" for linuxbridge-agent and "linuxbridge" for l3-agent.
