Hi All, I'm facing an issue in invoking Cloudinit while customization in RHEV 3.6 using RHEV Java SDK 3.6. Below link says we need to explicitly call *use_cloud_init=True*, but i'm not sure how to pass this value as parameter while creating VM. http://users.ovirt.narkive.com/BGUkanAk/ovirt-users-cloud-init-not-apply-whe... *My Code:* String password = "password"; //"password" String templateName = "centos6.7-final"; String clusterName = "Default"; String vmName = "testVM3"; //Prepare the data to create the VM from the template: org.ovirt.engine.sdk.entities.Template templateData = new Template(); templateData.setName(templateName); org.ovirt.engine.sdk.entities.Cluster clusterData = new Cluster(); clusterData.setName(clusterName); org.ovirt.engine.sdk.entities.VM vmDataForCreate = new VM(); vmDataForCreate.setName(vmName); vmDataForCreate.setCluster(clusterData); vmDataForCreate.setTemplate(templateData); api.getVMs().add(vmDataForCreate); String state; for (;;) { state = api.getVMs().get(vmName).getStatus().getState(); if ("down".equals(state)) { break; } Thread.sleep(1000); } System.out.println("System Status:"+state); org.ovirt.engine.sdk.entities.User userData = new User(); userData.setUserName("root"); userData.setPassword(password); Users usersData = new Users(); usersData.getUsers().add(userData); CloudInit cloudData = new CloudInit(); cloudData.setUsers(usersData); Host hostData = new Host(); hostData.setAddress(vmName); cloudData.setHost(hostData); org.ovirt.engine.sdk.entities.NetworkConfiguration networkConfiguration=new NetworkConfiguration(); networkConfiguration.setNics(new Nics()); Nics nics = networkConfiguration.getNics(); nics.getNics().add(createNic("eth0", "STATIC", createNetwork("192.168.1.102", "255.255.0.0", "192.168.2.1"), true)); networkConfiguration.setNics(nics); cloudData.setNetworkConfiguration(networkConfiguration); Initialization initData = new Initialization(); initData.setCloudInit(cloudData); VM vmDataForStart = new VM(); vmDataForStart.setInitialization(initData); Action actionData = new Action(); actionData.setVm(vmDataForStart); // Send the request to start the VM to the server: api.getVMs().get(vmName).start(actionData); -- Thanks & Regards Tejesh
