Reviewed-by: Juan Quintela <quint...@redhat.com> It is "infinitely" better that what we have. But I wonder if we can do better. We could just add a migration parameter that says _don't_ complete, continue running. We have (almost) all of the functionality that we need for colo, just not an easy way to set it up. Just food for thought. Later, Juan.
