Comment 1 for bug 1788634

As near as I can tell, numa_membw_values is never set. Maybe in some out-of-tree monitor? But it's certainly not set in https://github.com/openstack/nova/blob/cccba02be8dda0350a215de78b0acde3dbf19716/nova/compute/monitors/cpu/virt_driver.py#L42 which is where I'd expect it.
