I am testing virtlet in a CD. Frequent reset of kubernetes cluster and bringing up virtlet daemonset result in following error:

Could you please suggest any extra action, we have to take apart from Kubernetes reset ?

I believe that we can close this issue. This messages in log are harmless, while real issue behind this one was missing restart of kubelet after reconfiguration of its systemd service file.
