The RAM filter has been removed in recent versions of nova so there is
nothing to resolve on master now and it's unlikely to be resolved for
past releases. Closed as won't fix.
** Changed in: nova
Status: Confirmed => Won't Fix

Title:
ram_filter ignores hugepages which can create unstable guests
Status in OpenStack Compute (nova):
Won't Fix
Bug description:
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
