Issue/Introduction

- The deployment of an HCX Service Mesh fails with:
Service Mesh creation failed. Interconnect Service Workflow PrepareFleetPools failed. Error: Interconnect Service Workflow PrepareFleetNetwork failed. Error: Unable to create the HCX service mesh. Could not find an OVERLAY transport zone that is attached to all ESX hosts in the computed profile <Profile Name> deployment resources/container at site <site-name>

java.lang.RuntimeException: Interconnect Service Workflow PrepareFleetPools failed. Error: Interconnect Service Workflow PrepareFleetNetwork failed. Error: Unable to create the HCX service mesh. Could not find an OVERLAY transport zone which is attached to all ESX hosts in the compute profile <Profile-Name> deployment resources/container at site <Site-Name>

Environment

The affected environment has the following configuration:

- NSX is deployed in On-Premises and no Overlay-TZ is configured

- The WANOPT is selected during the Service Mesh deployment

Cause

When using a WAN Optimization appliance, an Overlay Transport Zone is required for communication between IX appliance and WANOPT appliance. This issue occurs if there is NSX on-premises and no overlay segment is configured in the ESXi hosts where WANOPT is deployed.

Resolution

- Deploy the service mesh without WANOPT

Or 

- Create a new overlay transport zone for the WANOPT.
