Set Up Your Local VMM

We’ll be using virtual machines (VMs) in this class, on the open-source VirtualBox platform. Here’s what you need to do, assuming you’re on Windows:

1. 1. 1. 1. Download and install 7zip so you can handle .7z files. As with all software, download it from the source, not from a mass download site.
            https://www.7-zip.org/download.html
         2. Download and install Oracle VirtualBox. Select the version for “Windows Hosts”, of course.
            https://www.virtualbox.org/wiki/Downloads
         3. Go to a site you’ll learn to love, OSBoxes:
            https://www.osboxes.org/
            Click on “VM Images”, then select “VirtualBox Images”.
            Download Ubuntu: plain, vanilla Ubuntu, not “Ubuntu MATE” or anything else. Just Ubuntu.
         4. Now watch this video, and do as the narrator does, EXCEPT:
            –>**Put your virtual machines, each in a separate folder, in C:\Users\Public\VirtualBox VMs **
