Indeed the underlaying problem is bug #1585165 and my issue is solved by applying mentioned patch. For some reason I did not find this other bug report previously. Thanks anyways! ** This bug has been marked a duplicate of bug 1585165 floating ip not reachable after vm migration -- You received this bug notification because you are a member of Yahoo!

I am using the Mitaka release with neutron DVR. 1) spawn a VM 2) assign a floating IP 3) live migrate the VM 4) ping the floating IP Using tcpdump I identified the reason for this problem: There is no gratuitous ARP reply sent out by the new host after live migration. Thus the network switch sends the traffic to the old host. If I manually send the GARP on the new host using: root@compute-2:~# ip netns exec fip- a46e0978-6e87-43d4-85d3-1d7030cdaf49 arping -A -I fg-de83cc57-32 FLOATING_IP the floating IP comes up again and everything works as expected.
