I think Lars has a page that describes this in good detail:

But the short answer to your question is to have a nodes.yml file that
looks like this:

-------------------------------------------------
extra_args: >-
  --ntp-server pool.ntp.org
baremetal_vm_xml: |
  <cpu mode='host-passthrough'/>
libvirt_args: --libvirt-type kvm

# Set these to values appropriate for your target system.  You
# by default get three controllers, one compute node, and
# one ceph node (so this example has a memory footprint of
# 32GB, which is probably too much for a host with only
# 32GB of RAM).
control_memory: 8192
compute_memory: 4096
undercloud_vcpu: 2

url: file:///usr/share/quickstart_images/mitaka/undercloud.qcow2

overcloud_nodes:
  - name: control_0
    flavor: control

  - name: compute_0
    flavor: compute
-------------------------------------------------
