Nested ESXi clone not able to assign IP and not pinging each other

Error:

Deploy a nested ESXi server.
Clone multiple nexted ESXi from this server.
When you assign IPs to all these ESXi, its not configuring and not pining.

Solution:

"Reset System Configuration" of each cloned/nested ESXi using the DCUI before applying the IP/hostname.

         After this root password will become empty password.
         Need to reset after login.
