I have code that does the necessary steps with Neutron to:
1. Create two networks (public and private) with subnets for each
2. Adds a router for the public subnet to attach it to the public network
3. Creates two VMs (RHEL, Centos, or Fedora) and attaches them to both
So, you should be able to use this setup to have DHCP listen on private
interface. Create a new host with no image and only connect it to the
private and it should PXE boot.
