No Windows VM Visible in Hyper-V for Windows Containers

When I run a Windows container with --isolation=hyperv on Windows 10 host OS (version 1803), I was expecting that it would spin up a Windows VM and run the container inside the VM, just like it spins up Linux VM for running Linux containers. But I dont see a VM running inside Hyper-V manager.

If it does not spin up a Windows VM for hyperv isolation mode, then what is the difference between running the container with --isolation=hyperv and --isolation=process mode?
