Creating a new virtual switch

Here is an example I use often. I am running this new Hyper-V Server, which is connected physically to my corporate network and so I can spin up new VMs, connect them to my external virtual switch, and have them communicate directly to the corp network. This allows me to domain join them, and interact with them like I would any server on my network. But maybe I have the need to create some VMs that I want to be able to talk with each other, but I do not want them to be able to communicate with my production network. A good example of this scenario in the real world is when building a test lab. In fact, I am taking this exact approach for all of the servers that we have used throughout this book. My physical Hyper-V Server is on my production network, yet my entire Contoso network and all of the VMs running within it are on their own separate network, which is completely segregated from my real network. I did this by creating a new private virtual switch. Remember...
