Hello Prasanna, Tests using listportforwardingrules are failing with latest marvin.
listportforwardingrules failed, due to: errorCode: 431, errorText:Unable to execute API command listportforwardingrules due to invalid value. Invalid parameter id value=c9373d55-3d01-480d-98dc-2365d3927378 due to incorrect long value format, or entity does not exist or due to incorrect parameter annotation for the field in api cmd class. I checked the listPortForwardingRules.py and found that "class tags" was added to this file resulting in the above failure. Marvin APIs are built from serverside API not sure how this "class tags" got added here. I have filed a bug: https://issues.apache.org/jira/browse/CLOUDSTACK-2577 Regards, Girish
