CreateL3FloatingIP: create L3 floating IP failed: %v

Error message

CreateL3FloatingIP: create L3 floating IP failed: %v

What it means

createL3FloatingIP wraps the l3floatingip.Create Extract failure when allocating a Neutron layer-3 floating IP. It fires when creation is rejected — no available IPs in the pool, quota exceeded, auth or network errors — and is retried with backoff before surfacing.
