use of org.btrplace.model.constraint.Running in project scheduler by btrplace.

the class GettingStarted method makeConstraints.

    // VM1 and VM2 must be running on distinct nodes
    cstrs.add(new Spread(new HashSet<>(Arrays.asList(vms.get(1), vms.get(2)))));

    // N3 must be set offline
    cstrs.add(new Offline(nodes.get(3)));
    // VM4 must be running, It asks for 3 cpu and 2 mem resources
    cstrs.add(new Running(vms.get(4)));
    cstrs.add(new Preserve(vms.get(4), "cpu", 3));
    cstrs.add(new Preserve(vms.get(4), "mem", 2));
