I had this exact problem too. After scratching my head for a while, I discovered my /etc/neutron/plugins/ml2/ml2_conf.ini was missing a section for [ovs]. I followed http://docs.openstack.org/icehouse/in... (read about half way down). After I added that section to my controller / network host and my compute nodes, things started working instantly.
