Docker + Virtual Box = VT-x is not available (VERR_VMX_NO_VMX)

Virtualbox will get upset and not run if Microsoft Hyper-V is enabled.

Here’s the solution:

1. Open command prompt as administrator
   • search for ‘command’
   • right-click then select ‘run as administrator’

2. paste the following command:

   dism.exe /Online /Disable-Feature:Microsoft-Hyper-V
   

3. Then reboot.
