I believe the post bellow will bring some more light on TripleO QuickStart
procedure suggested on RDO QuickStart page ( size of memory 32 GB
is a must. During minimal configuration runtime 23 GB of RAM are
required ). Following tips from Deploying OpenStack on just one hosted server
Overcloud deployed .

It won't work on 16 GB even minimal configuration.
Server memory allocation for minimal virtual environment
procedure suggested on RDO QuickStart page ( size of memory 32 GB
is a must. During minimal configuration runtime 23 GB of RAM are
required ). Following tips from Deploying OpenStack on just one hosted server
