This bug was fixed in the package nova - 2:14.0.0-0ubuntu1

---------------
nova (2:14.0.0-0ubuntu1) yakkety; urgency=medium

  * New upstream release for OpenStack Newton.
  * d/t/nova-compute-daemons: Skip test execution if running within a
    container, ensuring that autopkgtests don't fail on armhf and s390x.
  * d/t/control,nova-compute-daemons: Don't install nova-compute as part
    of the autopkgtest control setup, direct install hypervisor specific
    nova-compute packages ensuring packages are configured in the correct
    order and that nova-compute can access the libvirt socket.

Title:
  Nova hugepage support does not include aarch64

Status in OpenStack Compute (nova):
  In Progress
Status in nova package in Ubuntu:
  Fix Released
Status in nova source package in Xenial:
  In Progress

Bug description:
  [Impact]
  Although aarch64 supports spawning a vm with hugepages, in nova code, the libvirt driver considers only x86_64 and I686. Both for NUMA and Hugepage support, AARCH64 needs to be added. Due to this bug, vm can not be launched with hugepage using OpenStack on aarch64 servers.

  Note: this depends on the fix for LP: #1627926.

  [Test Case]
  Steps to reproduce:
  On an openstack environment running on aarch64:
  1. Configure compute to use hugepages.
  2. Set mem_page_size="2048" for a flavor
  3. Launch a VM using the above flavor.

  Expected result:
  VM should be launched with hugepages and the libvirt xml should have

    <memoryBacking>
        <hugepages>
          <page size='2048' unit='KiB' nodeset='0'/>
        </hugepages>
    </memoryBacking>

  Actual result:
  VM is launched without hugepages.

  There are no error logs in nova-scheduler.

  [Regression Risk]
  Risk is minimized by the fact that this change is just enabling the same code for arm64 that is already enabled for Ubuntu/x86.
