2016-11-22 14:47:53 -0600 asked a question OVS failed port after live migration

Hi Team, I'm using Mitaka cluster driver for Hyper-V with OVS 2.5 Windows port. When I perform live migration, an instance loses network connection but succesfully goes to another hosts. There was a bug in Liberty where ovs port had not been migrated to target hosts but now it is seems to be okay, ovs port is on target host but adds with errors.

vswitchd.log (migration time) https://paste.ubuntu.com/23510786/

nova-compute.log (migration time) https://paste.ubuntu.com/23510782/

nova.conf https://paste.ubuntu.com/23510815/

neutron-ovs-agent.conf https://paste.ubuntu.com/23510816/

If I execute the command (ovs-vsctl --timeout=120 -- --if-exists del-port 4b26fd63-e779-49c9-b419-ac2c53ef8c9a ....) logged in nova manually then I get network connection even without restarting the services.

I've also logged OVS debug rpc (another migration) and it contains "protocols":"OpenFlow10","datapath_version":"<unknown>"}

Please, help to investigate it.

Is there any nova.virt.hyperv.cluster.driver.HyperVClusterDriver release for Openstack Liberty? Is it possible to adapt mitaka driver for liberty release?
