Hello, Yes, removing the old DataCenter*.xml files from the /appdata/OneView/MyReports directory should resolve the issue. Or You can just re-name each of the DCM files in case you want to keep a back up: For example, mv DataCenterManagerAllHypervisors_IA.xml DataCenterManagerAllHypervisors_IA.xml.BACKUP You may need to "Refresh" (F5 button) the OneView Reports page in order to update the browser cache. They have fixed this in later builds yet to be released... Bill
