We ran into this issue too.

We tried to fix bug https://bugs.launchpad.net/keystone/+bug/968696 by changing policy.json. And at some point of time our service users had incorrect permissions. We noticed that network information disappeared from "openstack server list". But even after we fixed service user permissions, network information was not restored.

Investigation revealed that periodic jobs query list of ports from neutron. Neutron returned empty list because of bad service user permissions. Nova successfully deleted the ports from info_cache. We noticed that and restored permissions. Neutron started to return non-empty list again, but nova did not consume it.

We managed to fix it by changing code and forcing nova to record ports from the list.
