Minikube started from an GCE disk image #19587

What Happened?

Is it possible to have stable minikube cluster created with the following steps

  1. Create a VM instance on Google Compute Engine
  2. On ubuntu 20.04 LTS, start minikube (--api-server=VM_IP is passed in args)
  3. Deploy services
  4. Stop minikube
  5. Turn of GCE VM
  6. Create a disk image
  7. Create a new instance out of the created disk image
  8. Restart minikube with minikube start (--api-server=new VM_IP is passed in args)

After doing above steps, I can see my service pods up and running, but some of the kube-system pods go into error state. Once the pods enter error state, deleting the pods, does not fix the problem

Is there a way to recover this cluster? 

$ kubectl get pods -A

Can share more logs if at all using the minikube cluster from a vm created out of image is possible
