I am not sure whether flowtable of vm continue to work when OVN controller lost connection to OVN Database
If flowtable continue to work, can flowtable work after vm restart?
according to http://www.openvswitch.org//support/dist-docs-2.5/ovn-architecture.7.html section Life Cycle of a VIF, it looks that flowtable will not work after vm power off
Thanks for your reply
section Life Cycle of a VIF:
11.On every hypervisor, ovn-controller notices the empty Chassis column in the Binding table’s row for the logical port. This means that ovn-controller no longer knows the physical location of the logical port, so each instance updates its OpenFlow table to reflect that.
