Actually, no, I think you have it right (though the correct link is
I think the main work, though, has to be in removing/replacing the Nova
API /keypairs stuff with calls to Keystone's v3/credentials API.
Would the appropriate way to do this be to add an API shim into Nova's
API that simply calls out to the Keystone v3/credentials API IFF
Keystone's v3 API is enabled in the deployment? Then, deprecate the old
code and when Keystone v2 API is sunsetted, then remove the old Nova
keypairs API codepaths?
