Manuel,

Rather than with aggregate metadata we assign instances to NUMA nodes via flavor extra_specs,
i.e. nova flavor-show reports something like 

—>
| extra_specs                | {"hw:numa_nodes": "1"} | 
<—

for our NUMA-aware flavors. 

This seems to work pretty well and gives the desired performance improvement.

Cheers,
 Arne
