Unfortunately, I still need to use Windows to access applications for work. I turned my Win7 laptop on this evening to checkup on a few things and a similar screen to this appeared.
Being the impatient person I am, I fired up VirtualBox on the Mac and was greeted with the same screen.... Nearly 4 hours later its just completed.......
Arhhhhhhh
This is where I do my coding or development work mainly. Usually have two qterminals open. One for editing in Vim and another for running tests. Alternatively if I am working in Ecilpse then that will be open, likewise if I am running OSX in VirtualBox then that will be open instead. Or Windows for DevStudio.
Running Linux From a USB Drive As a Virtual Machine or Bootable Disk
Live Linux environments work just like a typical operating system but run entirely from a CD or USB stick — the latter being the most common choice these days. Since nothing is written to the host computer’s local storage, when you’re done all you need to do is remove the media, reboot, and everything will be exactly as it was.
There are a number of uses to this, from simply test driving Linux to troubleshooting a Windows PC, or work on the go from someone else’s computer but running your own OS securely with all your personal files and settings.
There are basically two options when it comes to running Linux from a USB drive: from within Windows using virtualization software such as VirtualBox, or creating a boot disk. This quick guide details both methods in a few easy steps.

Perhaps you just want to do something real quick without rebooting, or want to be able to hide the virtualized Linux instance. Our preferred weapon of choice here is a little tool called LinuxLive USB Creator.

- Download VirtualBox: www.virtualbox.org/wiki/Downloads
- Download Ubuntu 20.04.3 LTS: ubuntu.com/download/desktop/thank-you?version=20.04.3&...
- Install Ubuntu three times so that we will have 3 nodes for Kubernetes cluster. One Master node and other two as worker nodes.
- Create a NAT Network in Virtual Box (e.g. "Kubernetes Network") from Network preferences section. Use Network CIDR as 10.0.2.0/24
- Attach NAT network to all three instances
- Set the hostnames of VMs as following:
sudo hostnamectl set-hostname k8s-control for Master node
sudo hostnamectl set-hostname k8s-worker1 for Worker node 1
sudo hostnamectl set-hostname k8s-worker2 for Worker node 2
- Edit /etc/hosts file to include IPs of all three nodes. For e.g.
10.0.2.4 k8s-worker1
10.0.2.15 k8s-control
10.0.2.5 k8s-worker2
- Run Following Commands in each of the nodes
