I was following these great instructions, How to Create a Linux VM Using Hyper-V and when I got to the part where you actually create a new VM the computer frozed and restarted.  I tried this a couple more times with the same result.  I did a quick Google search and found this, Microsoft Forum Discussion on Samsung NVME Driver Issue .

In summary there was an issue with the Samsung Storage Controller driver version 2.1 that was causing the OS to crash when creating a new VM using Hyper-V.  You can check your current driver version by
1. Go to Start
2. Search for Device Manager
3. Expand the Storage Controllers node in the Device Manager
4. Double click on Samsung NVMe Controller to launch the details
5. Go to the Driver page and look at the Driver version.

The good news is that Samsung has released a fix for the issue with version 2.2 which you can download directly from Samsung at http://www.samsung.com/semiconductor/minisite/ssd/download/tools.html (just go to the Driver section for the installer and instructions).

After running the installer and restarting my machine the Hyper-V Manager successfully created my new VM.
