In Utilitarianism Mill argues that virtue not only has instrumental value, but is constitutive of the good life.  A person without virtue is morally lacking, is not as able to promote the good. However, this view of virtue is someone complicated by rather cryptic remarks Mill makes about virtue in his A System of Logic in the section in which he discusses the “Art of Life.”  There he seems to associate virtue with aesthetics, and morality is reserved for the sphere of ‘right’ or ‘duty‘.  Wendy Donner notes that separating virtue from right allows Mill to solve another problem for the theory: the demandingness problem (Donner 2011).  This is the problem that holds that if we ought to maximize utility, if that is the right thing to do, then doing right requires enormous sacrifices (under actual conditions), and that requiring such sacrifices is too demanding. With duties, on Mill's view, it is important that we get compliance, and that justifies coercion.  In the case of virtue, however, virtuous actions are those which it is “…for the general interest that they remain free.”
