[Rdo-list] Deploying RDO using Foreman

Hi, I posted a question regarding "Deploying RDO using Foreman" to ask.openstack.org and thanks to Keshyap and Rich which engaged me to proceed further, I updated the thread here: https://ask.openstack.org/en/question/12104/deploying-rdo-using-foreman/ The post might be too long, here some more information about the reason behind my question and some more questions: I'm trying to learn Foreman for installing OpenStack and use it to deploy RDO on top of RDO to provide some kind of OpenStack training / webinars and later to run the whole thing on 6-8 bare metal machines and use it to deploy OpenShift and write a tutorial about the whole thing and post it on the RDO site, LinkedIn, etc. About our BASE RDO environment: Our RDO based 3 node environment is thanks to the latest update very stable and very fast now and I've to thank all of you smart guys for doing such a great work! Our environment uses VLAN and the Foreman RDO installation shall use GRE and Qemu (or LXC / Docker) to let us play with the whole thing and write a tutorial about the whole thing. So my questions: Does the Foreman installation on top of a virtualized environment work at all? (I guess yes) Could a VLAN based BASE-Install be a problem to succeed with this scenario (to have GRE on top of VLAN)? (I guess no) Has someone tried such a scenario before? (I guess yes) Could I use LXC / Docker instead Qemu? Thanks in advance for any help / advice! Arash
