Comment 4 for bug 1654203

There is a problem with neutron server configuration - the driver extension lists are different.
node-4 (the updated one I presume) has dns,port_security enabled while the rest have either port_security (nodes 1-3) or port_security,qos (node 5) enabled. http://paste.openstack.org/show/594542/

As Roman has stated in https://bugs.launchpad.net/fuel/+bug/1628540/comments/7 , there should be no discrepancy between neutron server configuration on different nodes.
