[Users] [rhevm-api] Assign IP address to VM using Java SDK

[Tejesh M]

Hi All,

Thanks alot.

I have created one VM with minimal installation & installed cloud-init
package. And, converted that VM into Template. Then executed the code given
in http://lists.ovirt.org/pipermail/users/2014-February/021302.html , but
no luck, the code is not setting root password.

Also, there is no option to set *Hostname *for the VM.



*Code:*

        /*********************Begin Customize VM*********************/
        // Generate the random password, using whatever mechanism you
          // prefer:
          String password = "cJql3P9XLQG4drCYVG/6Q/";

          // You need to know the name of the template, the cluster and
          // the VM you are going to create:
          String templateName = "rhel2_temp";
          String clusterName = "testCluster";
          String vmName = "myvm";

          // 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);

          // Send the request to create the VM to the server:
          api.getVMs().add(vmDataForCreate);
          String state;
          // White till the VM is down (it will be locked for a while):
          for (;;) {
             state = api.getVMs().get(vmName).getStatus().getState();
            if ("down".equals(state)) {
              break;
            }
            Thread.sleep(1000);
          }
          System.out.println("System Status:"+state);
          // Populate parameters for the action to start the VM with
cloud-init:
          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);

          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);
          System.out.println("After :
"+api.getVMs().get(vmName).getStatus());
          /*********************End Customize VM*********************/



Thanks & Regards,
Tejesh
