br-int (br-vlan and br-tun - depending on what modes you are using as well) should get created automatically by opensvswitch-agent on startup. br-ext you should create manually via your os's init scripts.

Observed one more thing that even if I dont have any bridges configured , If I restart the openstack I see br-int gets created.
Thanks,
Dev

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"
