I can see the problem is in HostMO.getLocalDatastoreOnHost. My datastore (as well as the NFS datastore that was automatically created to download an ISO) shows up as DatastoreSummary.isMultipleHostAccess == false (along with a couple other fields) and this qualifies it as "local" storage.
I believe I've never seen this before because vCenter Server probably changes DatastoreSummary.isMultipleHostAccess to true when you have more than one host in the cluster that can access the datastore (I usually have more than one host in a VMware cluster, but don't right now). It seems DatastoreSummary.isMultipleHostAccess is not sufficient to use to declare if something is local storage.
