vxlan and internal interface from vm

I have 2 VMs (VM1, VM2) on a ESXi server-1.

I want to have these 2 VMs talking so i have created one vnic on each and connected using same port-group and gave them subnet, say

192.168.0.0./24.

Its working fine.,

I want to have VM1 talk with another VM (VM3) in another ESXi server-2 on the same subnet 192.168.0.0/24.

So i created a vxlan virtual wire.

Now my question is: how do i connect them together.

Should i put the vnic of VM1 in the virtual-wire?  If i put then the VM1-VM2 connection is lost.

Should i create another vnic in VM1 and put that in the virtua-wire?  If i do that, then how can i have this new vnic in the same subnet

as the VM1-VM2 subnet (192.168.0.0/24) ?
