Comment 5 for bug 1567114

I think what might be happening is CONF.osapi_max_limit defaults to 1000 and that's the default limit when listing flavors. When you just pass the flavor name, novaclient is trying to lookup the flavor, which in this case is doing an index request to the nova API. What I'm not sure about is if it's hitting a limit and not actually using the filter, i.e. if there are already 1000 flavors in the database and you're searching for a flavor by name after those 1000, is it returning the first 1000 and not actually applying the name filter?

When you run this, can you add the --debug option to the nova boot command since that should show the flavor request/response details and that would be helpful when it fails.
