My private port groups have no vlans yet as there's no communication across the switch. I knew this would be the issue, just wanted to confirm.
How is your physical switch setup and how many uplinks do you have from your Distributed vSwitch on each host? The communication between guests on different host is something that should not be an issue, and could in your case be caused by the switch set up on the physical side or possible from the portgroup settings.
Could you post a screenshot of the Distributed vSwitch and the private VM portgroups?
