I'm trying to clone a VM from snapshot with the below code. but it is not cloning..

      org.ovirt.engine.sdk.decorators.VM vm2 = api.getVMs().get("testVM");
          VM cloneVM = new VM();
          cloneVM.setName("MyClonedViaAPI");
          VMSnapshot snap3 = new VMSnapshot(null);
          snap3 = vm2.getSnapshots().get(UUID.fromString("7799ce3f-a007-415a-84c5-df323e8f440d"));
          Action act = new Action();
          act.setClone(true);
          act.setVm(cloneVM);
          snap3.restore(act);
