You can definitely delete a flavor [1].

Don't worry about it affecting existing instances that were created with
that flavor: nova stores a copy of the flavor with the instance itself
so the information is preserved.

Is this the case also if the extra_specs field attribute was set for the flavor and the AggregateInstanceExtraSpecsFilter filter is used ?

Aren't there problems rescheduling an instance created with that flavor ?

Thanks, Massimo
