Public bug reported:
The IP address filtering logic implemented in the compute API can duplicate
instances if a given instance either:
- Has a fixed IP address in more then 1 network that matches the filter
- Has more then 1 fixed IP address in the same network matches the filter
For example:
$ nova list
+-----+-----------------+-------------------------------------------------+
| ID | Name | Networks |
+-----+-----------------+-------------------------------------------------+
| 123 | InstanceTest | gre_shared_1=192.168.0.11; network=194.168.0.14 |
| 456 | InstanceOne | gre_shared_1=192.168.0.3 |
+-----+-----------------+-------------------------------------------------+
$ nova list --ip 19
+-----+-----------------+-------------------------------------------------+
| ID | Name | Networks |
+-----+-----------------+-------------------------------------------------+
| 123 | InstanceTest | gre_shared_1=192.168.0.11; network=194.168.0.14 |
| 123 | InstanceTest | gre_shared_1=192.168.0.11; network=194.168.0.14 |
| 456 | InstanceOne | gre_shared_1=192.168.0.3 |
