error finding port %s: %v

Error message

error finding port %s: %v

What it means

During instance creation, a 'port already in use' error was returned and the code attempted to look up the referenced port, but the Neutron GetPort call itself failed. The port lookup is part of recovery from a stale-port bug; this error means the recovery path could not even inspect the port.

Solutions

1. Verify the port ID exists: openstack port show <portID>
2. Check Neutron API health and credentials
3. Manually delete the stale port if it was left over from a deleted instance, then retry
