Open Stack

In my setup I have deployed everything on real hardware with VLANs etc
to mimic production style. Are you trying to deploy openstack-ansible
(AIO)? https://docs.openstack.org/openstack-ansible/latest/user/aio/quickstart.html

Let me assume you are trying to deploy an openstack-ansible AIO model
on a virtual box. In that case you don't need any special networking,
all you need is a single virtualBox nic in Bridge mode and follow AIO
instructions. Why don't you join openstack-ansible IRC, it's hard to
answer interactive questions here.
