have u tried with latest minikube version ? @anuragp0010

there seem to be something wrong with your virutalbox setup I recommend eitehr reinstalling it

Meanwhile have you tried out newest driver Docker Driver with latest version of minikube?
you could try
minikube delete
minikube start --driver=docker

for more information on the docker driver checkout:

Hopefully it's OK if I close this - there wasn't enough information to make it actionable, and some time has already passed. If you are able to provide additional details, you may reopen it at any point by adding /reopen to your comment.

Here is additional information that may be helpful to us:

  • Whether the issue occurs with the latest minikube release
  • The exact minikube start command line used
  • The full output of the minikube start command, preferably with --alsologtostderr -v=3 for extra logging.
  • The full output of minikube logs

Thank you for sharing your experience!
