BearGolightly, I have double checked with our engineering team, and have confirmed that DirectPath I/O is in fact not supported with PA-VM series devices on ESXi.

We are working with our team to make sure that all documentation and references to DirectPath I/O are updated to reflect the correct information. Please let me know if there's anything else I can help you with.
