Public bug reported: If you reload/restart the neutron-openvswitch daemon it will first throw away all existing flows. This will break all networking until the flows are re-created.
It can take some time before everything is back in the flow table on machines with quite a bit of instances or a busy neutron server. Please make the clearing of the flows optional during a restart. ** Affects: neutron Importance: Undecided Status: New ** Tags: neutron-openvswitch-agent ** Tags added: neutron-openvswitch-agent ** Summary changed: - Restarting openvswitch daemon causes network hiccup by throwing away all flows + Restarting neutron openvswitch agent causes network hiccup by throwing away all flows -- You received this bug notification because you are a member of Yahoo!
