[rdo-list] [TripleO] Newton large baremetal deployment issues

[Charles Short]

Hi,

Unfortunately I am under some pressure to get my stack into production, 
so now have OSP9 running. I have little opportunity for more testing of 
Newton.
If I get a window I will send you the info

Regards

Charles
