hosts can not ping each other on the same DPortGroup

Hello,

 

I only have one physical server within 172.18.211.0/24 network, I want to establish a embedded vsphere environments inside the physical server.

1. The physical server has 8 physical network adapters (vmnic1 to vmnic7), the default deployment created a vswitch0 has connected with vmnic0 which is in 172.18.211.0/24 network.

2. I created two ESXi VMs connected with VM Network portgroup of vswitch0 (this is a virtual standard switch), each ESXi VMs has twovirtual network cards like below, and I configured both of ESXi VMs with 172.18.211.X IP address

3. I added these two ESXi host to a Vcenter, and created a virtual distributed switch DSwitch in database. I added two ESXi VM hosts in this DSwitch like below:

4. Because each ESXi VM hosts has two virtual network cards NIC, thus I used one network card NIC of each ESXi VM host as virtual distributed switch DSwitch uplink, like below (uplink 1, uplink 2)

5. I created one CentOS 7 VM in each ESXi VM host, and both of them are connected within DPortgroup, like below:

6. I started up both CentOS 7 VMs and configured both VMs within the same network, for example 192.168.10.0/24

 

7. Problem: Then it revealed the problem that both CentOS7 VMs can not ping with each other.

8. My Guess: Is this problem cause by building virtual distributed switch on virtual standard switch? therefore two CentOS 7 vm can not ping with each other.

 

Questions:

1. so why the Two CentOS 7  can not ping each other?

2. Could I use this environment to test NSX and iSCSI, if I create more ESXi VMs on the physical hosts? since I have not tried.

 

Hope someone could guide me a bit, I am new to vsphere, and trying to learn more about vsphere.

Thank you much in advance.
