Hyper-V: Adds vNUMA implementation

[OpenStack Infra]

https://review.openstack.org/282407
Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
Your project "openstack/nova" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

    Hyper-V: Adds vNUMA implementation

    vNUMA can improve the performance of workloads running on virtual machines
    that are configured with large amounts of memory. This feature is useful
    for high-performance NUMA-aware applications, such as database or web
    servers.

    Returns Hyper-V host NUMA node information during get_available_resource
    Adds validation for instances requiring NUMA topology (no asymmetric
    topology and no CPU pinning supported).
    Creates NUMA aware instances, if necessary.

    The compute-cpu-topologies page in the admin-guide will have to be
    updated to include Hyper-V NUMA topologies usage and configuration.

The NUMA docs say that only the libvirt driver supports NUMA topology, but in the 15.0.0 Ocata release, the hyper-v driver also supports NUMA:

Hi Claudiu and Matt,

Could you please update this bug report for manuals with the the following:

1. What doc does this change effect?
2. What is required to be updated?
3. Is this for Mitaka/Newton/Ocata?

Thanks,

Alex

Hi,

I've sent the patch for the docs update a few weeks ago: https://review.openstack.org/#/c/424102/

3. Ocata.

    Adds Hyper-V NUMA topology documentation

    The commit Iba2110e95e80b9511698cb7df2963fd218264c8e introduced
    the ability to spawn NUMA-aware instances on Hyper-V compute nodes.

    Updates the compute-cpu-topologies to include information about
    Hyper-V compute nodes configuration and instance creation restrictions.
