Public bug reported:
Env: Ussuri environment with 1 controller + 2 compute nodes.
Reproduce steps:
1. Create a VM at comp;
2. Live-migrate the VM from comp to comp2;
3. Live-migration success;
4. Live-migrate the VM from the comp2 to comp;
5. Live migration fail
I find that there are duplicate records in the neutron's
"ml2_port_bindings" table:
MariaDB [neutron]> select * from ml2_port_bindings where
port_id="71c3a3c7-d853-4b26-9975-50b99c449371";
+--------------------------------------+-------+----------+-----------+---------------------------+---------------------------------------------------------------------------------------------------------------------------+----------+

+--------------------------------------+-------+----------+-----------+---------------------------+---------------------------------------------------------------------------------------------------------------------------+----------+
| 71c3a3c7-d853-4b26-9975-50b99c449371 | comp | unbound | normal |
{"migrating_to": "comp2"} |
| INACTIVE |
| 71c3a3c7-d853-4b26-9975-50b99c449371 | comp2 | ovs | normal | {}
| {"connectivity": "l2", "port_filter": true,
"ovs_hybrid_plug": false, "datapath_type": "system", "bridge_name": "br-int"} |
ACTIVE |
+--------------------------------------+-------+----------+-----------+---------------------------+---------------------------------------------------------------------------------------------------------------------------+----------+
After removing the "INACTIVE" record, I do the step4( live migrate the
VM from host2 to host1 ) success.
I find a similar bug at https://bugs.launchpad.net/nova/+bug/1822884.
But it seems that it is different from this bug.
