Open Stack

Hello,

When I tried devstack with Neutron Ryu plugin, nova boot failed with
the following error:
ERROR: The server has either erred or is incapable of performing the
requested operation. (HTTP 500) (Request-ID:
req-2f3489c9-9fb5-4666-b5a3-dabf8068160b)

Change Iaaee059a (https://review.openstack.org/#/c/49455/) added the
validation of the port quota via Neutron API.
However, AFAIK, Neutron Quota API was implemented as an API extension,
so this API is not provided when we use Neutron plugin which does not
support Quota extension.
Is this Nova's bug? Or should Neutron provide Quota API always?

I attached detailed log.

Thanks,
Kaneko
