<p>I have a virtual machine with Minikube inside it.<br>
It works great when I run it using <code>minikube start --vm-driver=none</code> command.  </p>

<p>My host crashed and therefore also the virtual machine. I rebooted the host and then the virtual machine and when I tried to run minikube  it failed with lots of information:  </p>

Unfortunately, an error has occurred:
    timed out waiting for the condition

This error is likely caused by:
    - The kubelet is not running
    - The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)

If you are on a systemd-powered system, you can try to troubleshoot the error with the following commands:
    - 'systemctl status kubelet'
    - 'journalctl -xeu kubelet'

Additionally, a control plane component may have crashed or exited when started by the container runtime.
To troubleshoot, list all containers using your preferred container runtimes CLI, e.g. docker.
Here is one example how you may list all Kubernetes containers running in docker:
    - 'docker ps -a | grep kube | grep -v pause'
    Once you have found the failing container, you can inspect its logs with:
    - 'docker logs CONTAINERID'

minikube failed :( exiting with error code 1
</code></pre>

<p>When I run <code>minikube status</code> I received:  </p>

<pre><code>host: Running
kubelet: Running
apiserver: Stopped
kubectl: Correctly Configured: pointing to minikube-vm at 10.240.0.23  
</code></pre>

<p>It seems that there is problem with the API server.  The kubelet server is running but has errors like that:  </p>

<pre><code>kubelet.go:2266] node "minikube" not found
</code></pre>

<p>I run <code>minikube logs</code> and I see the same errors:  </p>

<pre><code>://localhost:8443/api/v1/nodes?fieldSelector=metadata.name%3Dminikube&amp;limit=500&amp;resourceVersion=0: dial tcp 127.0.0.1:8443: connect: connection refused

</code></pre>

<p>It seems that it has some problem to connect to 127.0.0.1:8443 and therefore send error that the "minikube" not found.  </p>

<p>I saw that this issue was already mentioned <a href="https://github.com/kubernetes/minikube/issues/2967#issuecomment-423915639" rel="nofollow noreferrer">here</a> but I tried the solution and it didn't work for me.<br>
I stopped minikube and delete it and start it over again but the same problem appear.  </p>

<p>Any idea what is the reason for this ?  </p>

<p>I solved it like that:  </p>

<pre><code>minikube stop &amp;&amp; minikube delete
docker rm -f $(docker ps -aq)
reboot
</code></pre>

<p>After reboot it started correctly.<br>
But I still didn't understand how it could be fixed without the restart.<br>
The restart is was the missing piece. If you would do these command without restart and try to start it again, it won't start.  </p>
