I don't have a simple answer yet. We're still eliminating options. Right now our long list still stands at: Foreman, Redhat's ManageIQ EMC, UrbanCode's Terraform, CloudBolt C2, vCloud Automation Center, BMC's Cloud Lifecycle Management, and IBM's SmartCloud Orchestrator. Most of these use libvirt and one of Puppet, Chef, or Salt under the hood.
