VM Tunnel network is nothing but a seperate network which should be configured in dedicated NIC card. So that all the communication (packets transfer) between all VM in the entire openstack setup communicate through that dedicated NIC which will not affect the other data (packets) transfer between management networks and external networks.

It is also possible to use management IP as tunnel IP in test environment.

To configure management IP as Tunnel IP :

Add the below configuration at /etc/neutron/plugins/ml2/ml2_conf.ini in all the compute & neutron nodes.


local_ip = <management IP> or < Dedicated IP with DedicatedNIC >

So from my understanding, You are trying to setup openstack on VMware ESXI machine. You have created 3 VMs on ESXI host. So if it is. try the following. I hope you added additional vNIC to all the 3 VMs. Make sure all the 3 VMs is now have 2 vNICs. So You should see the 2nd NIC is listing in VMs

When you able to see the 2nd NIC added to your VMs.Then follow the usual setup for opnestack install and then follow the steps in the answer I have posted.
