How to get Docker for Windows running inside a Hyper-V Virtual Machine

- Create your VM as normal, get Windows installed and so on
- Power the VM down, to "Off" state
- On the HOST pc, execute the following 2 commands from an elevated Powershell prompt

Set-VMProcessor -VMName "Name of your VM" -ExposeVirtualizationExtensions $true
Get-VMNetworkAdapter -VMName "Name of your VM" | Set-VMNetworkAdapter -MacAddressSpoofing On

- Start up the VM again
- Inside the VM, execute the following command from an elevated Powershell prompt

Enable-WindowsOptionalFeature -Online -FeatureName $("Microsoft-Hyper-V", "Containers") -All

(reboot of the VM might be necessary)

After this, proceed to install and use Docker for Windows as normal.

Profit!
