Glad that the patch works for you. For the instance_id and flavor_id, I'm not sure which table are you talking about. But I think flavor_id is same as "instance_type_id", while instance_id is purely an id for an instance, which is usually created based on an instance_type (or, flavor).

I was able to get it to work with your changes. I am a little confused by the terminology of "instance_id" and "flavor_id" in the tables. Either their meaning is crossed or I am not reading it right.

I wrote a little python script to create a flavor id and set_key using the new RESTful apis that you defined. After creating the flavor, when I try to set the key I am getting error message from the nova side. Do I need pick to any changes from nova side to make it work? I can send you my sample code and error message privately or put it on the mailing list if that helps.

Also, make sure you add a scope (where scope is a string followed by a `:' at the beginning of the key) to whatever key you are adding to the extra specs table, otherwise your key will create problems with some of the scheduler filters. -- Don Dugger "Censeo Toto nos in Kansa esse decisse." - D.

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. 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?

Best regards, Patrick 2012/8/24 Dugger, Donald D <donald.d.dug...@intel.com<mailto:donald.d.dug...@intel.com>> Patrick- We've enhanced `nova-manage' to manipulate the `extra_specs' entries, c.f. https://blueprints.launchpad.net/nova/+spec/update-flavor-key-value, You can add an `extra_specs' key/value pair to a flavor with the command: nova-manage instance_type add_key m1.humongous cpu_type itanium And delete a key/value pair with the command: nova-manage instance_type del_key m1.humongous cpu_type We're in the process of enhancing `python-novaclient' and Horizon with similar capabilities and hope to have them ready for the Folsom release. Currently, there's no hook to set `extra_specs' through the `nova.conf' file, the mechanism is to dynamically add the `extra_specs' key/values after the administrator has created a flavor. Currently, the keys are completely free form but there are some issues with that so that should change. Checkout the bug: https://bugs.launchpad.net/nova/+bug/1039386 Based upon that bug we need to put some sort of scope on the keys to indicate which components a key applies to. I'm in favor of adding a new column to the `extra_specs' table that would explicitly set the scope but an alternative would be to encode the scope into the key itself, something like `TrustedFilter:trust' to indicate that the `trust' key only 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. -- Don Dugger "Censeo Toto nos in Kansa esse decisse." - D.

If how extending an instance type is relatively clear. Eg.: #nova-manage instance_type set_key --name=<my.instancetype> --key <cpu_arch> --value <'s== x86_64'> The principles of capability advertising is less clearer. Is it assumed that the key/value pairs are always declared statically as flags in nova.conf of the compute node, or can they be generated dynamically and if so, who would that be? And also, are the keys completely free form strings or strings that are known (reserved) by Nova? Thanks in advance for clarifying this.
