Public bug reported:

If I understand correctly, the concept of flavor extra specs has been
replaced by metadata.

On nova/virt/hardware.py, it's checking for some specific flavor extra
specs in _get_cpu_topology_constraints().

https://github.com/openstack/nova/blob/f396826314b9f37eb57151f0dd8a8e3b7d8a8a5c/nova/virt/hardware.py

These specific flavor extra specs are included in the pre-defined
metadata json so the user can load them with command "glance-manage
db_load_metadefs". However, the names are not exactly the same.

https://github.com/openstack/glance/blob/1c242032fbb26fed3a82691abb030583b4f8940b/etc/metadefs
/compute-vcputopology.json
