Yes, the intent has been to use something along the lines of <div>"OS-FLV-EXTRA-DATA:disk_qos"</div><div><br></div><div>This leads to another question which I saw being discussed earlier in the email thread. Are we looking for consistency in adding the extra specs? For the most obvious ones it may be worth while to come up with a standardized convention for the names.
</div><div><br></div><div>I was looking at the code and it appears that the extra_specs and the instance_types creation don't have similar code flow. When you delete a instance_type that you created with extra_specs (using the set_key method in nova-manage), the extra_specs are not cleaned up. I would have thought that they should go away too, right? Unless I understood the concept of extra_specs wrong. </div>

<p class="MsoNormal">We would like to add flavor types in which we specify the blkiotune in the create flavor screen. After reviewing the discussions and some emails it appears that it makes sense to use the "instance_type_extra_specs" to add the blkiotune
as a key/value pair instead of extending the "instance_type" table in nova db. <u></u><u></u></p>

<p class="MsoNormal">I am able to use nova-manage to create instance type and use "set_key" to add extra specs. The set_key seems to make a direct call to the db to insert the keys whereas the instance_type create takes the more traditional path through the
flavomanage controller. However I notice that there is no documentation on how to add the extra_specs keys using a RESTful api. Is this something still in discussions? <u></u><u></u></p>

applies to the `TrustedFilter’ scheduler component. Feel free to chime in on the BZ entry on how to specify the scope, once we decide on how to deal with this I’ll create a patch to handle it.</span><u></u><u></u></p>
