public class vmcre
{
public static void main(String args[])
{
try
{
  Client oneClient = new Client();

//  I dont know whether i have to change this source path or not even i
dont do any changes on this but it will not work


    String vmTemplate =

        + "FEATURES = [ acpi=\"no\" ]";

    System.out.print("Trying to allocate the virtual machine... ");
    OneResponse rc = VirtualMachine.allocate(oneClient, vmTemplate);

    if( rc.isError() )
    {
        System.out.println( "failed!");
        throw new Exception( rc.getErrorMessage() );
    }
    int newVMID = Integer.parseInt(rc.getMessage());
    System.out.println("ok, ID " + newVMID + ".");

    VirtualMachine vm = new VirtualMachine(newVMID, oneClient);

    System.out.print("Trying to hold the new VM... ");
    rc = vm.hold();

    if(rc.isError())
    {
        System.out.println("failed!");
        throw new Exception( rc.getErrorMessage() );
    }

    rc = vm.info();

    if(rc.isError())
        throw new Exception( rc.getErrorMessage() );

    System.out.println();
    System.out.println(
            "This is the information OpenNebula stores for the new VM:");
    System.out.println(rc.getMessage() + "\n");

    System.out.println("The new VM " +
            vm.getName() + " has status: " + vm.status());

    System.out.println("The path of the disk is");
    System.out.println( "\t" + vm.xpath("template/disk/source") );

    rc = vm.finalizeVM();
    System.out.println("\nTrying to finalize (delete) the VM " +
                        vm.getId() + "...");

}
