VirtualBox Installation on macOS

VirtualBox Installation

Running virtualization on your laptop/desktop or home lab provides an easy way to learn and test various operating systems, including AWS EC2 instances. Also, it can serve a development environment for testing code and configurations. While there are various virtualization solutions such as VMware, VirtualBox offers a free solution that is well supported in the open source community.

Amazon Linux 2

Useful Linux image to run locally is Amazon Linux 2 which is the default Linux when you provision an AWS EC2 instance. Great and free way to test your image before you deploy live.

Setup

Instructions can be found at https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/amazon-linux-2-virtual-machine.html

Note: Select the instructions for Oracle VirtualBox

Recommended network configuration

Since most of this is used for development and testing, I recommend using the DHCP option. Configuration is below.

local-hostname: amazonlinux
# eth0 is the default network interface enabled in the image. You can configure static network settings with an entry like the following.
network-interfaces: |
  auto eth0
  iface eth0 inet dhcp

VirtualBox Tips

Do not allow VirtualBox to limit screen size as it may be difficult to read. To change the display settings, select Preferences -> Display -> Maximum Guest Screen Size should be set to None.

VirtualBox Networking Chart
