I care about 80% of the ports and I tried dvs_object.FetchDVPorts(criteria) using as scope criteria the host but this criteria seems to be deprecated in 6.0 and for all ports beside the uplink ones the scope is Unset making the fetch return ports from all hosts.
Having a way to fetch only vDS ports of VMs from a certain host might help me because I might use parallel queries to get only the ports connected to a certain host. The final form in which I need this data are per host based.
