Hi-

While enabling VM with huge pages, I get the following error.

2017-02-01 18:02:14.305 ERROR nova.scheduler.utils [req-e9408e8e-bbb5-499f-ab71-07ae694b23b0 admin alt_demo] [instance: 82bf7e7c-d835-4624-845d-2bd0dbdd0a11] Error from last host: openstack (node openstack): [u'Traceback (most recent call last):\n', u'  File "/opt/stack/nova/nova/compute/manager.py", line 1783, in _do_build_and_run_instance\n    filter_properties)\n', u'  File "/opt/stack/nova/nova/compute/manager.py", line 1938, in _build_and_run_instance\n    instance_uuid=instance.uuid, reason=e.format_message())\n', u'RescheduledException: Build of instance 82bf7e7c-d835-4624-845d-2bd0dbdd0a11 was re-scheduled: Insufficient compute resources: Requested instance NUMA topology cannot fit the given host NUMA topology.\n']

I'm using devstack (stable/newton) and nova (6.0.0).

I have configured hugepages and flavors following the guide at http://docs.openstack.org/admin-guide/compute-huge-pages.html

Kindly please help me resolve this issue.
