How to set reserved_huge_pages in /etc/nova/nova.conf in Red Hat OpenStack Platform
https://access.redhat.com/solutions/3250441 instructs to configure reserved_huge_pages, but how can this parameter be set with Red Hat OpenStack Director?

reserved_huge_pages has a specific format which makes it difficult to use crudini or the built-in nova_config puppet type. Parameter name reserved_huge_pages needs to be set per NUMA node:

[DEFAULT]
reserved_huge_pages=node:0,size:1GB,count:4
reserved_huge_pages=node:1,size:1GB,count:4
