If you want to set up more than one lab, say, on a desktop and a laptop, feel free to jump back to the previous recipes for installing VirtualBox 6.0 on Windows or Mac. If you do so, you'll need to run through the virtual machine creation recipes and need to install the tools, dependencies, and code examples on all of the hosts you'll use for a lab.
