Currently, when attaching neutron pre-existing
port to an instance, if the attach failed, it
will also be deleted in Neutron side due to
bad judgement of the who created the port by
reading not up-to-date info_cache.
The workflow starts at:
https://github.com/openstack/nova/blob/9ed0d6114/nova/network/neutronv2/api.py#L881
ordered_ports and preexisting_port_ids are
the same when attaching a preexisting port
to an instance and it calls
https://github.com/openstack/nova/blob/9ed0d6114/nova/network/base_api.py#L246
which calls back into the neutronv2 api code
https://github.com/openstack/nova/blob/9ed0d6114/nova/network/neutronv2/api.py#L1274
and at this point, compute_utils.refresh_info_cache_for_instance(context,
instance) won't have the newly attached port in it(see
debug log: http://paste.openstack.org/show/613232/)
because _build_network_info_model() is going to
process it. The instance obj in memoryt with old
info_cache will be used at rollback process and
causing the miss-judging.
This patch fixed it by updating instance.info_cache
to the new ic after it is created.
