External Networks Unavailable while Deploying Instances in Clarity UI

Problem

• Unable to use external networks to create instance via Clarity UI
• Networks configured with router:external pointing to External are not able to be utilized while creating VMs on PMO.

Environment

• Platform9 Managed OpenStack: All Versions
• Clarity UI

Cause

• The provider network was created as an external type via enabling router:external that caused filtering out of the network to be inspected for available subnet IP allocations.
• Clarity UI restricts directly provisioning VMs from networks from an External as they are intended to be used to provide floating IPs.

Resolution

• Disabling router:external or pointing it to False comes in as a workaround for the network to be used while deploying an instance.
• This can be done by editing into the desired network and uncheck the External Network field.
