class DisabledInstanceTypesTestCase(*args, **kwargs)

Bases: nova.tests.compute.test_compute.BaseTestCase

Some instance-types are marked ‘disabled’ which means that they will not show up in customer-facing listings. We do, however, want those instance-types to be available for emergency migrations and for rebuilding of existing instances.

One legitimate use of the ‘disabled’ field would be when phasing out a particular instance-type. We still want customers to be able to use an instance that of the old type, and we want Ops to be able perform migrations against it, but we don’t want customers building new slices with ths phased-out instance-type.
