Doc Text:
This release adds support for PCI device NUMA affinity policies, which are configured as part of the “[pci]alias” configuration options. Three policies are supported: “required” (must have) “legacy” (default; must have, if available) “preferred” (nice to have) In all cases, strict NUMA affinity is provided, if possible. These policies allow you to configure how strict your NUMA affinity should be per PCI alias to maximize resource utilization. The key difference between the policies is how much NUMA affinity you're willing to forsake before failing to schedule. When the “preferred” policy is configured for a PCI device, nova uses CPUs on a different NUMA node from the NUMA node of the PCI device, if it is available. This results in increased resource utilization, but performance is reduced for these instances.

Comment 1 Stephen Finucane 2017-04-27 12:17:30 EDT 
This RFE focuses on making NUMA affinity for SR-IOV/PCI devices optional. The spec missed the Pike deadline so this has been deferred to Queens.
Comment 2 Stephen Finucane 2017-08-30 12:02:26 EDT 
As (hopefully) noted previously, this is being taken care of by a Mirantis guy. I plan to keep an eye on this this cycle and step in if necessary.
