In my lab cluster, I first activated Microservices. Then, I created a VPC followed by setting up an Overlay subnet. Finally, I attached my VMs for internal communication. However,: the VMs aren't acquiring IP addresses on the subnet configured within the Overlay subnet. Even after manually configuring the IP addressing, there is no communication between the VMs.

It sounds like you might be missing one of the required open ports between the Prism Central and the AHV hosts. I believe this is either 6652 or 6653. You can check the ports and protocols page to make sure all of this communication is allowed.

I should also note that Flow Virtual Networking is available in the NCI Ultimate or NCI Pro licensing tiers, but this behavior you are seeing does not seem related to licensing.

I believe it's a licensing issue.

Thanks
