Comment 14 for bug 1291396

Exact filters looks great . Will test it soon.

Do you think, you could also add some filter to match Flavor extra specs to Ironic node metadata? I am not sure how this should be done yet. :-) But we could use it for matching architecture and e.g. tags we will put to Ironic nodes.
This is probably worth a bp, if there is not already filter, that can do this.
