I have done 3 node deployment of openstack liberty on cent os 7 and
configured neutron with ml2 and ovs. when am trying to spin up instances
getting neutron error unable to bind port to  host am pasting logs files
and ml2 conf file below

These are the steps followed to create ovs bridges

I have 2 physical interface eth0 is management and eth1 is trunk for all
public/vlan/vxlan traffic
 ovs-vsctl add-br br-uplink
ovs-vsctl add-br br-vlan
 ovs-vsctl add-br br-int
 ovs-vsctl add-port br-uplink eth1 -- set port eth1 vlan_mode=trunk
 ovs-vsctl add-port br-vlan patch-to-uplink -- set Interface
patch-to-uplink type=patch options:peer=patch-to-vlan
 ovs-vsctl add-port br-uplink patch-to-vlan -- set Interface patch-to-vlan
type=patch options:peer=patch-to-uplink
vs-vsctl add-port br-uplink l3vxlan tag=4000 -- set Interface l3vxlan
 ip addr add 10.255.255.XXX/24 dev l3vxlan
ip link set dev l3vxlan up
 ip link set dev l3vxlan mtu 1600
