Open Stack

Just as a heads up, we are removing the default flavors from nova in
this patch:

Since long ago, Nova's default flavors were baked in at the database
migration level. Now that we have moved them to another database
entirely, this means we have to migrate them from the old/original place
to the new one, even for new deployments. It also means that our tests
have flavor assumptions that run (way too) deep.

Devstack will get support for auto-creating the flavors you are used to,
as well as some less-useless ones:

Normal developers shouldn't really notice, but the deployment tool
projects may want/need to do something here along the same lines.
