Quota classes are a feature I introduced to nova.  The intention was to
link them up to group information that would be presented via Keystone,
but by the time anything analogous to a group was added to Keystone, I
had moved on to other, higher priority projects, and I was unable to
come back and add the necessary support.  That was several releases ago,
and quotas in general keep coming up at each of the summits, in the
context of a thorough, cross-project rototilling and possible creation
of a new quota management project (either as part of Keystone or on its
own, a la Boson).

If you'd like to make use of quota classes, I'm afraid it will require
writing some code.  You will need to create a piece of middleware which
will sit after the keystonecontext filter in /etc/nova/api-paste.ini.
It will need to get the context (req.environ['nova.context']) and set
the "quota_class" attribute to the name of the quota class.

Hopefully eventually we'll make some progress on truly supporting quotas
and file off all these burrs, but it's not an easy problem, so in the
meantime…
