Iam deploying newton HA cluster with separate node for neutron , controller and compute nodes. Iam using vxlan tunnelling with openvwitch agent. Everything seems to be fine except network part. While launching instance it get IP for some time and then dies with error "No valid host was found. There are not enough hosts available Code 500". Then I checked my /var/log/neutron/neutron-openvswitch-agent.log in compute node and I found that whenever I restart the openvswitch agent by service neutron-openvswitch-agent restart iam getting error as below but it shows as up in neutron-agent list from controller node.
