Hi Darragh, Thank you for your advise! It worked like a charm!
That's it, after adding: root@hyperstack-1:~# cat /etc/init/neutron-ovs-cleanup.conf start on starting nova-compute or neutron-plugin-openvswitch-agent script /usr/bin/neutron-ovs-cleanup end script Compute Node can be rebooted and all its Instances, gets its IPs immediately after node restarts. Thanks!!!
