Communication trouble of CVM when building CE on Nested ESXi

Dear All, I am trying to build Nutanix CE into the environment of Nested ESXi.
I downloaded and prepared the latest version of ce - 2018.05.01 - stable.img.gz. The ESXi to build the AHV is 6.0.
First of all, we started to work as a single node cluster, we plan to develop into a 3 node cluster if it works.
192.168.0.27/24 to AHV, GW: 192.168.0.254. I set up CVM 192.168.0.28/24, GW: 192.168.0.254 and started the installation.
After waiting for a while, a message stating that the installation was successful is displayed and the message "Nutanix CVM IP: 192.168.0.28" is displayed.
However, only AHV can communicate with this CVM, and it can not communicate with other devices on the same subnet.
If you check the Arp Table of another Linux machine on the same subnet, the correct MAC address of CVM is registered but the MAC address of this Linux machine is not registered in the Arp Table of CVM side. Only the MAC Address of AHV is registered in the Arp Table of CVM.
CVM can not communicate with Gate Way and can not connect to the external network, so we can not proceed with construction work. Please teach someone what kind of cause is considered.
