Is this a BUG REPORT or FEATURE REQUEST?:

Uncomment only one, leave it on its own line:

/kind bug

/kind feature

What happened:

While debugging (a probably unrelated) issue, I found these log lines which might be a bug, so I thought I'd report them:

I1019 07:43:31.502200 11 loadbalancer.go:1691] "Load balancer ensured" lbID="dbeba37e-aa8e-45a2-bc76-a812e8d58df3" isLBOwner=true createNewLB=false

What you expected to happen:

no internal error :)

How to reproduce it:

No idea. But might need to use the OVN provider.

Anything else we need to know?:

Sorry for the terrible report, I have no idea what this is about - just saw an unexpected log line (that appears quite frequently).

Environment:

• openstack-cloud-controller-manager(or other related binary) version: v1.30.0
• OpenStack version: Zed?
• Others: load-balancers API 2.26
