This Kilo feature is needed in addition to Juno NUMA related features for deployment of VMs requiring high I/O performance. We would need to get it backported to OSP6 to get full performance:
The NUMA locality of I/O devices is another important characteristic to consider when configuring a high performance, low latency system for NFV workloads. This blueprint aims at combining NUMA based PCIe device information with the CPU/NUMA related topology info included in the juno release. This optimises Openstack guest placement by ensuring that a guest bound to a PCI device is scheduled to run on a NUMA node that is associated with the guests pCPU and memory allocation.
