The host configuration report doesn't specify the datastores and stuff.
I really think a license compliancy report would be a major asset in the reporing tool. We all have SQL, sybase, oracle, sharepoint, iis, ... and all of us have to have some licensing spreadsheet. An error in the placement of a vm could have hughe consequences because for instance an oracle that can boot on the wrong cluster equals $$ x CPU.
So I think it could end up on the wishlist to have a report that gives me a list of all my vm's with their name, vcpu number, their cluster, cpu's in cluster, and maybe the extra possibility to add an extra line that states that vm could not be 'very' easily be vmotioned because the datastore is not presented to the other vmware cluster.
Licensing gives us sometimes really bad configs because every vendor has it's own rules towards cpu, clustering...
