Github user sateesh-chodapuneedi commented on the issue: https://github.com/apache/cloudstack/pull/1868 The point of specifying a host is in deploy request itself means inclination towards using that host for instance. Hence I think default value should be false. While global setting makes sense, rather than a global setting, it would be better to add optional parameter in API itself which indicates whether deploy should strictly try deployment on specific host, if any, or look for other hosts as well. That way more granular control in case by case perspective.
