test_server_connectivity_cold_migration_revert failing

Bug Description

test_server_connectivity_cold_migration_revert has started failing now that we've un-skipped it [1]. It appears as though Nova is doing everything right in terms of external events and VIF plugging (see analysis on PS6 of [2]), so the thinking is that it's something with the Neutron L3 agent. Sean Mooney's noticed that the guest does get an IP from DHCP, but then we fail to ping the VM from tempest.

This bug is filed under Neutron, but that's more of a placeholder based on preliminary guessing. We can easily change it to Nova or some other component once we understand better what's going on.

@Artom: Hi, is this still an issue or can we maybe close this? I don't see issues like that in any neutron gate job at least.
