That is true David. This feature collates available patches for all the Xen hosts managed by CloudStack from a central repository which is updated as and when a patch is available for a version of XenServer and presents a neat report of which patches are already applied on a given host and which are not across various versions of a host. What it does not do is to "apply patches". That is left to tools that do a better job. Instead of sharing the credentials of all his/her Xen hosts to an external monitoring system a Cloud Admin can have CloudStack provide a single central interface to these external software like zabbix. This to me makes integration with third party software like zabbix, zenoss much easier and meaningful. It is an operational nightmare for an Admin to key in credentials of all his/her hosts to both CloudStack and his external management systems. This feature can be supported across other elements managed by CloudStack as long as those elements provide a standard protocol to share the patch details. Also please note scalability is not a concern here as we are not looking at providing real time updates. Thanks, Ram
