up to the scheduler. You can then use the extra_specs to specify key/value pairs for a flavor that will be used by the scheduler’s compute_capabilities’ filter to make decisions based upon these capabilities. Note you can do relational comparisons on these
capabilities, look at:<o:p></o:p></span></p>
