Error Creating Tenant Network: "Unable to create the network. No tenant network is available for allocation."

Problem

The following error is encountered when attempting to provision a tenant network: "Unable to create the network. No tenant network is available for allocation."

Environment

• Platform9 Managed OpenStack - All Versions
• Clarity UI
• OpenStack CLI

Cause

The VXLAN VNID Range is exhausted – the maximum number of tenant networks has been reached.

Resolution

1. In Clarity UI, navigate to Networks > Networking Config.
2. Expand the VXLAN VNID Range – setting it to a high enough value such that there is sufficient capacity for additional tenant networks to be created.
   
   
   Note: Each tenant network will allocate 1 VNID.
