- update engine configuration (use ovirt-config --set KEY_NAME=KEY_VALUE): * ExternalSchedulerServiceURL=http://<host>:18781/ * ExternalSchedulerEnabled=true - restart ovirt-engine service. - under configure->cluster_policy see that the balance function was added (should be in manage policy units- you will see it in the main dialog as well). - clone current cluster's used cluster policy (probably none - prefer it to have no balancing modules to avoid conflicts), name it 'your_name' and set it with the external function - replace cluster's cluster policy with newly created one (in edit cluster dialog).
