This bug seems to me a duplicate of https://bugs.launchpad.net/neutron/+bug/1456073.

There were couple of patches for this bug that was fixed in Mitaka.

There is still a patch in Nova that has not merged to address this issue.

I should need to triage this bug and see if this is still exhibiting the same behavior. The issue that I noticed when we live migrate is we send the GARP from the floatingip namespace that is created on the new node and so the external entity that is trying to reach the floatingip will now try to ping both and then the first one would fail, since we already removed the floatingip from the first node and will succeed from the second node.
