There are 3 related fields(id, uuid and hostname) in ComputeNode[1]. according to [2], after nova api 2.53, the id of the hypervisor as a UUID. and service.host is equal to hypervisor name for compute node. so we can remove id and only keep uuid then set uuid to node.id [1]:https://github.com/openstack/watcher/blob/master/watcher/decision_engine/model/collector/nova.py#L306 [2]:https://developer.openstack.org/api-ref/compute/?expanded=list-hypervisors-details-detail#list-hypervisors-details Change-Id: Ie1d1ad56808270d936ec25186061f7f12cc49fdc Closes-Bug: #1835192 Depends-on: I752fbfa560313e28e87d83e46431c283b4db4f23 Depends-on: I0975500f359de92b6d6fdea2e01614cf0ba73f05
