Title:
Unable to delete instances created using stale networks
Status in OpenStack Compute (Nova):
Invalid
Bug description:
I am on Kilo.
I was using VxLAN based networks.
As the lab requirement changed, I had to move over to "FLAT" networking.
This involved editing the ml2_conf.ini file and the necessary changes for
'flat' networking to work.
However, I didn't enable VxLAN networking any longer - even though the
networks pre-created (using VxLAN) were still lying there. (This wasn't
intentional).
Again without actual intentions, I ended up deploying an instance with the
VxLAN based networks.
This results into a build failure on the compute node with the following
exception:
Unable to clear device ID for port 'None'

The bind failed because of the following error:
Network a813e9e3-4e87-4de6-8f48-84e4a4cb774a is of type vxlan but agent or
mechanism driver only support ['local', 'flat', 'vlan'].
check_segment_for_agent
/usr/lib/python2.7/site-packages/neutron/plugins/ml2/drivers/mech_agent.py:193
which is clear and expected.
Post this, I wanted to clean up the instances and it just won't get deleted.
Even though the delete request comes back with "Request to delete server has
been accepted"
Upon pdbing, I could see that there's an error being thrown at the
nova/api/openstack/wsgi.py around line 1061 -
"'Controller' object has no attribute 'versioned_methods'"
I think this is a different bug than the ones which have been earlier
reported.
Bug 1329559 being one for reference.
