While setting up and starting minikube in my lab How to Install Minikube on Ubuntu - Step by Step, I was receiving two errors. First error was related to not running minikube start as root privileges. Which was resolved after existing from the root account and running minikube as a normal user.
But another error occurred related to Intel VT-X/AMD-V not enabled after running minikube start again.

To resolve the error of virtualization not enabled in CPU, I opened Edit Settings of Virtual Machine, in the Virtual Hardware expand CPU and enabled check box of Hardware virtualization --> Expose hardware assisted virtualization to the guest OS. In case if the system is bare metal enable virtualization in BIOS. (System will require reboot).
Once the configuration is done, start minikube and get the list of nodes.
