Public bug reported:
environment info:
OS：centos7.1
nova:15.0.2
problem description:
There are 220G memory in compute-node.The 200G of them are hugepages.The
page_size is 1G.
Other 20G of them are normal memorys.
When I boot a normal instance with the flavor of 30G mem and no hugepages.
The instance is created successfully.But the OS become unstable even OOM
because memory exhausted
I think the instance should boot failed with ram_filter return 0 hosts.Rather
than think that the memory is sufficient
and spawn the instance in that compute_node
