Moving to ON_DEV as while testing locally with this patch https://review.openstack.org/#/c/620053/ I successfully scaled out from 1 compute to 2 computes.
Patch has been merged upstream
To verify: 1) Delete the stack: openstack stack delete overcloud --wait --yes 2) In ~/virt/nodes_data.yaml - Change: ComputeCount: 1 3) Deploy: ./overcloud_deploy.sh 4) Once it is deployed, change in ~/virt/nodes_data.yaml: ComputeCount: 2 5) Redeploy: ./overcloud_deploy.sh
