====== VirtualBox Linux Lab ======
The mission is this Lab is to create genuine hands-on experience for hands-on learnings who want to learn to use Ansible to create auto-installing Ubuntu ISOs and use them to stand up a server lab in Oracle VirtualBox.

Mission:
  * Install Ansible and other required packages on a new Ubuntu system
  * Prepare ssh keys for managing the Ansible servers
  * Install VirtualBox using Ansible
  * Customize the user-data for unattended installation
  * Create a custom Ubuntu server ISO that automatically installs
  * Deploy our first Ubuntu VM to OracleBox
  * Test our first Ubuntu VM
  * Delete our first Ubuntu VM
  * Deploy our first fleet of VMs
  * Deploy an application to our fleet of VMs

Materials:
  * NUC
    * Recommend a more powerful NUC with 16GB RAM and 500GB disk space
      * Most mid-range NUCs have 4 physical CPUs for a total of 8 cores. Most Gen12 and Gen13 NUCs have more cores available.
    * Yes you can create an VM in VMware and run Oracle Virtualbox...
      * __IF__ you enable "Virtualize Intel VT-x/EPT or AMD-V/RVI" under Settings > Processors in VMware
      * __BUT__ However, I had issues the network connectivity on the Oracle guests, both bridging and NATting. Setting the promiscuous mode settings on the Virtualbox guest didn't solve the issue.
