Hi Chris, Thank you for your reply, and really sorry for delay. Cause I did not notice this mail without Cc me. The spec file is cloned from https://github.com/openstack/nova-specs.git. It looks same to your link. > >2) You are asking whether these APIs are now stable enough to be used in >nova, since you want to propose some mechanism to allow them to be changed. > >Is that accurate? Yes, your understanding is right.
