Thanks for reply from André
The switch EtherChannel configuration isn't be misconfigured, 'cause pESXi can communicate with LAN / WAN or storage devices normally.
This strange problem can be solved by setting x2 uplinks to x1 uplink of vESXi, then pESXi and vESXi can ping normally with each other.
But, I'm really want to know whether the vSwitch of vESXi can be configured NIC teaming (IP-Hash or portID) to pESXi vSwitch or not.
