using the template : ansible/vars/16.2_fencing_3combo_dpdk_sriov.yaml
with osp 17 configs is not taken in to account.
OSP deployment fails , and although the template specifies :

osp_release_defaults:
  vmset:
    ControllerSriov:
      count: 3

the output is only controller: 1

[root@titan131 yamls]# grep 'roleCount\|roleName' ctlplane/osp-director_openstackcontrolplane.yaml 
      roleName: Controller
      roleCount: 1

so in install_ctlplane.yaml the combined osp_dict does not pick that role count up :

• name: Set combined osp dict
  set_fact:
  osp: "{{ osp_defaults | combine((osp_release_defaults | default({})), recursive=True) | combine((osp_local | default({})), recursive=True) }}"

although when I alter the osp_defaults: controller: to be 3 in vars/default.yaml
it is picked up by the make ctlplane.
Reproducer and live env is on titan131 on the tmux or under the dir :
/home/rhos-ci/jenkins/workspace/DFG-ospk8s-osp-director-dev-tools-qe-16.2_hybrid_nfv_sriov_dpdk/openstack-k8s/openstack-k8s/ansible
env variable used is : OSP_RELEASE=16.2_fencing_3combo_dpdk_sriov
