Adding the Operators list to this since I think they will have some useful
comments.

My experience is that the current Nova quotas are not entirely useful. In
our environment we have a limited number of machines with 32 cores and 1TB
of ram (tens), and a large number with 8 cores and 32GB of ram (hundreds).
Aside from limits on the # of instances, the quota system would see the use
of 32 small machines as equivalent to the use of one big machine.
Economically and operationally these to cases are very different.

As a suggestion, how hard would it be to allow operators to create quotas
on the # of a given flavor that a tenant/domain may want to use?
