How to mess up your virtualization on Windows 10

For the past year, I’ve been getting to know virtual machines (VMs). 

I’ve mostly been using VirtualBox on Windows 10 and Parallels on my Mac. A few weeks ago I thought it was time to also explore Windows Hyper-V. So, I turned it on. Big mistake – activating Hyper-V deactivated my ability to run 64-bit VMs within Virtual Box. Which was a problem, as I have an instructional set of model VMs set up on my classroom computer, which were then exported for use on the student computers, And I had about a week invested in creating these particular model VMs (installed software, settings, model networks. etc).

Now, I did the two things (activate Hyper-V) and then revisit my VirtualBox VMs about a week apart. So it took me a bit of time (and googling) to work back and determine what i needed to do. 
Although I went in and turned off the Hyper-V features within Apps and Features > Program and Features > Turn Windows Features On or Off, I also ran PowerShell commands to make sure it was good and off and wouldn’t come back on when I next updated my classroom computer system. 

The key thing I learned was that the reason the two virtualization applications don’t work well together is that Hyper-V is a Type I hypervisor for Windows 10 – and VirtualBox is a Type II hypervisor running within Windows 10.
