[ACS 4.2][Upgrade Issue] System VM template caching

Hi, 

Several of us in the community have found that with the 4.2 upgrade, when we download and install the latest system VM template, CloudStack refuses to use this template for new system VM creation. CloudStack appears to be usin a cached or master-clone variant of the old template. 

This is causing may KVM+ 4.2 users to have broken clouds, A bug report has been filed: https://issues.apache.org/jira/browse/CLOUDSTACK-4826 

My question is: Does anyone know where this cached template is stored? when CloudStack goes to make a new system VM, where does it look first for the template? We have observed through testing that this is no secondary storage. 

Thanks in advance.

This seems similar to a problem I had on 4.3 Master with System VM creation. If it is the same problem you can check from API command ListTemplateCommand(), from CloudMonkey and see if it returns a bogus cached value. Then you know it is the same problem.
