[rdo-list] TripleO on single machine

I am trying to set up a machine for learning TripleO on, but I'm still confused on whether a single machine can be used for a practice configuration. I have made a few runs building Packstack on it, not really happy with how any turned out, and really need to work with TripleO since that's what I'd be supporting. I have a baremetal system with RHEL 7.4beta on it, 128G memory and 32 cpu/cores, so it should be able to handle a decent training configuration. Is it even possible to do this on this system, or perhaps I should be creating a number of simple KVM/QEMU instances manually and building from there?
