Hi guys, I've been attaching and detaching interfaces to an instance until
I got into a weird situation:

-I see the interface:

root at cocinero:~/tools# nova --os-username noc-admin --os-tenant-name noc
--os-password My_Pass --os-auth-url http://172.19.136.1:35357/v2.0
interface-list c7d4e004-47fc-42b4-9aec-83e196f9c202
+------------+--------------------------------------+--------------------------------------+--------------+-------------+
| Port State | Port ID                              | Net ID
                | IP addresses | MAC Address |
+------------+--------------------------------------+--------------------------------------+--------------+-------------+
| ACTIVE     | 572cb037-c0b7-490b-b451-594897817397 |
275c5c97-5a18-41ff-a46c-49d78507fb22 | 172.16.28.34 |             |
+------------+--------------------------------------+--------------------------------------+--------------+-------------+
root at cocinero:~/tools#

-I want to delete that interface, so:

root at cocinero:~/tools# nova --os-username noc-admin --os-tenant-name noc
--os-password My_Pass --os-auth-url http://172.19.136.1:35357/v2.0
interface-detach c7d4e004-47fc-42b4-9aec-83e196f9c202
572cb037-c0b7-490b-b451-594897817397
root at cocinero:~/tools#

No error messages at all.

-But the interface stills there:

root at cocinero:~/tools# nova --os-username noc-admin --os-tenant-name noc
--os-password My_Pass --os-auth-url http://172.19.136.1:35357/v2.0
interface-list c7d4e004-47fc-42b4-9aec-83e196f9c202
+------------+--------------------------------------+--------------------------------------+--------------+-------------+
| Port State | Port ID                              | Net ID
                | IP addresses | MAC Address |
+------------+--------------------------------------+--------------------------------------+--------------+-------------+
| ACTIVE     | 572cb037-c0b7-490b-b451-594897817397 |
275c5c97-5a18-41ff-a46c-49d78507fb22 | 172.16.28.34 |             |
+------------+--------------------------------------+--------------------------------------+--------------+-------------+
root at cocinero:~/tools#

Doing some research I've found this bug
https://bugs.launchpad.net/nova/+bug/1326183 , which is exactly the same
behaviour I see in my cloud. It seems to be related to a race condition
during the cache update.

Any ideas how to:

-Reset the conditions so I can detach the interface cleanly?
-Backport the proposed patch to Grizzly? (Upgrading to IceHouse is almost
impossible)

Thanks!
