Nithin made a good suggestion. It would help to know where the packet is getting dropped. Can you collect wireshark traces on both the VM¹s and the HV NICs and let us know where the packet gets dropped? We suspect that this might be a checksum offload issue, so disabling offloads on the VM & the PNIC might just do the trick.
