Cannot Disassociated Autoallocated floating ip

[seth vidal]

When you've allocated a floating ip to an instance you cannot disassociate the old ip from the instance.

Any attempt to do so ends in an error.

You should be able to disassociate the auto-allocated floating ip from an instance.

Can you include the details of the error you get? Thanks

ERROR: Cannot disassociate auto assigned floating ip (HTTP 403) (Request-ID: req-cbafd77d-92e0-4ee4-b462-82dc4bf3fefe)

that instance has:

 vlannet_5=172.16.5.3, 209.132.184.143, 209.132.184.154 |

the first ip there is the one I associated with it from my set of floating ips I'd allocated before.

I need this instance to have a persistent ip across many instantiations and reboots.

I don't need 2 external ips allocated to it.

Nova doesn't authorize to delete an auto assigned floating IP. As was explained in this bug https://bugs.launchpad.net/nova/+bug/1061499
You got the same problem without attache a second floating IP to the VM interface.

But in bug https://bugs.launchpad.net/nova/+bug/1061499, Dan Prince (comment #1) asks to reconsider treating auto-assigned floating IPs just like we do normal floating IPs and allow them to be unassigned. So we can use this bug to discuss it and if we are OK, to implement it

Another bug related to this topic https://bugs.launchpad.net/nova/+bug/1017379
Perhaps we can link these bugs ?

After looking at this and talking about it more, I don't think this is something we can rush in for grizzly. We need more time to look at all the ways that auto assigned floating IPs are special cased and make sure we're not breaking things if we change it.

Fix proposed to branch: master

[Édouard Thuleau (ethuleau)]

I made a fix which authorize to disassociate an auto-assigned floating IP on a server.
- the auto-assigned floating IP is listed in floating IP list
- when an auto-assigned floating IP is unassigned from a server, it is automatically deallocated from the project
- when a server with an auto-assigned floating IP is deleted, the auto-assigned floating IP is automatically deallocated from the project
