All:
I have installed and configured neutron (using the official docs, my
openstack version is icehouse and the OS is centOS7.
After creating the neutron network and started the instance the instance
goes to the ERROR state and says "no Valid host found"
/var/log/neutron/openvswitch-agent.log Shows below:
