    List<Instance> instances = new ArrayList<>();
    Model m0 = new DefaultModel();
    m0.getMapping().addReadyVM(m0.newVM(1));

    m0.getMapping().addOnlineNode(n1);
    m0.getMapping().addRunningVM(m0.newVM(2), n1);
    Model m1 = new DefaultModel();
    Node n2 = m1.newNode();
    Node n3 = m1.newNode();
    m1.getMapping().addOnlineNode(n2);
    m1.getMapping().addOnlineNode(n3);
    m1.getMapping().addReadyVM(m1.newVM(3));
    m1.getMapping().addSleepingVM(m1.newVM(4), n2);
    m1.getMapping().addRunningVM(m1.newVM(5), n3);
    instances.add(new Instance(m0, new ArrayList<>(), new MinMTTR()));
    instances.add(new Instance(m1, new ArrayList<>(), new MinMTTR()));
    Set<VM> all = new HashSet<>(m0.getMapping().getAllVMs());
    all.addAll(m1.getMapping().getAllVMs());
    TIntIntHashMap vmIndex = Instances.makeVMIndex(instances);
    // Only VMs in m0
    Gather single = new Gather(m0.getMapping().getAllVMs());
    Assert.assertTrue(splitter.split(single, null, instances, vmIndex, new TIntIntHashMap()));
    Assert.assertTrue(instances.get(0).getSatConstraints().contains(single));
    Assert.assertFalse(instances.get(1).getSatConstraints().contains(single));
    // All the VMs, test the unfeasibility
    Gather among = new Gather(all, false);
    Assert.assertFalse(splitter.split(among, null, instances, vmIndex, new TIntIntHashMap()));
}
