For the specific case you're looking for though, you could use the Placement REST API: http://docs-draft.openstack.org/32/470932/5/check/gate-placement-api-ref-nv/771f604//placement-api-ref/build/html/?expanded=show-resource-provider-detail,show-resource-provider-inventory-detail Using ^ you could get the VCPU resource class inventory allocation ratio for a given resource provider, where an example of a resource provider is a compute node. For a compute node resource provider, the uuid is the same as the compute_nodes.uuid field and the name is the compute_nodes.hypervisor_hostname field. Note that we don't expose compute node uuids out of the compute REST API yet, but I'm working on that here: https://review.openstack.org/#/c/471899/ -- Thanks, Matt
