[openstack-dev] [Nova] Flavor ID consistency

I would like to gather some thoughts for fixing the issue https://bugs.launchpad.net/python-novaclient/+bug/1089299.


1.       The documentation (http://api.openstack.org/api-ref.html) and the CLI help text (for flavor-create) suggests that only a unique integer value is acceptable as flavor identifier. However, a flavor can be created by specifying a non-integer identifier. Also, if the create flavor API is not provided with an identifier, it generates a UUID (alphanumeric) identifier. Does the documentation and help text need a relook?

2.       If alphanumeric identifiers are allowed, the CLI failure (for instance of flavor with non-integer and non-UUID identifier) on 'show <instance-id>' needs a fix?

Is fixing the CLI failure on 'show' command the correct fix for this issue?

Another related issue is the absence of an Update Flavor API. Due to this, what currently happens is when a user edits a flavor from the Dashboard, a new flavor gets created which has a UUID (and the original flavor ID is marked deleted). Are there any specific reasons for this behavior?
