Doc Type: Enhancement
Doc Text:
With this update you can now configure NUMA affinity to ensure instances are placed on the same NUMA node as the NIC providing external connectivity for the vSwitch. This feature is available for layer 2 networks of type 'flat' or 'vlan' and layer 3 networks of type 'vxlan', 'gre', or 'geneve'.

can we get a non-private summary of this RFE please?
Comment 5 Stephen Finucane 2019-04-23 09:09:54 UTC 
This tracks effort to backport the NUMA-aware vSwitches feature added in OSP 14 (rhbz 1187945) to OSP 13. In summary, physical NICs typically use the PCIe interface and have an association with a host NUMA node. This feature allows us to associate networks using a given NIC with that NIC's NUMA node and therefore associate any instances using these networks with the same NUMA node.
