Public bug reported:
Description
===========
There are some system processes which use hugepage when compute node starts.
But when we report numa_topology resources, we do not consider these. And we
do not consider it by reserving hugepage.
Expected result
===============
Used NUMAPagesTopology information in compute node is all system used hugepage.
Or we can consider it by reserving hugepage mem.
Actual result
=============
Used hugepage information in compute node is not correct. It can cause select a
host which can not build a instance using hugepage.
Environment
===========
Os which supports KVM and hugepage. And we build instance which uses hugepage.
Logs & Configs
==============
Flavor include extra_specs hw:mem_page_size=1048576 which instance uses.
