Service mesh fails to create when source and destination sites are configured to use distributed portgroups

Products

• VMware HCX

Issue/Introduction

• When creating an HCX service mesh, the an error similar to the following is generated:
  

  Unable to create Service Mesh

  Switch: ###### of type: VmwareDistributedVirtualSwitch is not supported for remote sites having NSX-T; only Overlay Transport Zones are supported.

  
  
  

Environment

• HCX 4.11.x
• HCX Source and destination site network profiles use distributed port groups (running on a vNetwork Distributed Switch, VDS) instead of NSX segments backed by an overlay transport zone.
• One or more of the following services are configured in the compute profile and service mesh:
  
  • WAN Optimization
  • Network Extension
  • V2T Migration
• An NSX overlay transport zone is not configured at the destination site.

Cause

The WAN Optimization, Network Extension, V2T Migration services require an NSX overlay transport zone to function properly. When these services are enabled during service mesh creation, a check is made against NSX to ensure that there is a configured overlay transport zone. If one does not exist, the service mesh cannot be created.

Resolution

If the WAN Optimization, Network Extension, V2T Migration services are not needed, disable them in the compute profiles and service mesh. If they are needed, an NSX overlay transport zone must be configured at the destination site and the compute/network profiles be updated to use the appropriate NSX-backed segment.
