Title:
Instance Termination delays in updating port list
Status in OpenStack Neutron (virtual network service):
New
Status in OpenStack Compute (Nova):
New
Bug description:
When deleting an instance, the port list is not updated immediately.
As a result - deleting net/subnet fails with error:
409-{u'NeutronError': {u'message': u'Unable to complete operation on
subnet UUID. One or more ports have an IP allocation from this
subnet.', u'type': u'SubnetInUse', u'detail': u''}}
(*) Happens only on automated scripts, since manual input isn't quick
enough to catch this.
(**) Happens only when Floating IP is attached - error doesn't happen when Floating IP isn't used.
my guess: Nova delays in deleting the VM while checking with neutron DB that Floating IP was deleted.
(***) nova delete command returns BEFORE instance is deleted:
> nova delete $instance_id ; nova show $instance_id
will return the instance without failure
(*****) might also affect Tempest during tearDown execution

How to reproduce:
**** script attached ****
assumes:
1. external network exists with floating ip range available ("public")
2. image exists
Setup:
1 create network "private"
2. create subnet
3. create router:
3.1 set router gateway to "public"
3.2 set router interface to "private"
4. create VM
5. assign Floating IP to VM
TearDown
1. Delete / Disassociate Floating IP
2. Delete VM
3. detach router interface from subnet (router-interface-delete)
4. Delete subnet/net
Expected Result:
subnet/net should be successfully deleted.
Actual Results:
"Unable to complete operation on subnet UUID. One or more ports have an IP allocation from this subnet"
409-{u'NeutronError': {u'message': u'Unable to complete operation on
subnet UUID. One or more ports have an IP allocation from this
subnet.', u'type': u'SubnetInUse', u'detail': u''}}
script log:
line 101 - VM port still in port list even though VM was deleted
line 105 - subnet fails to delete
line 117 - network successfully deleted after enough time passed for port list to update
