C9800-CL for my homlab

Introduction After the release of the new Catalyst 9800 Controller, I see that the virtuell version support the same features as the hardware. In order to perform simple tests outside my lab in the future, I wanted to run the controller virtually on my MacOS. Since there are 1-2 small stumbling blocks here, I created this blog post. Prerequisites I tested the installation under VMWare Fusion and VirtualBox on my Mac. VMWare Fusion runs stable with all options. Under VirtualBox I first had problems with the network card.
