Enable "Virtual Machine Platform"

[UnwantedFeature]

When starting the test-nodes with vagrant up --provider=virtualbox, the process exists with an error telling me to enable "Virtual Machine Platform". This feature is already enabled.

PS D:\Projects\Vagrant\WindowsDomain\test-nodes> vagrant up --provider=virtualbox

Virtual Machine Platform is installed:

PS C:\Windows\system32> Get-WindowsOptionalFeature -Online | Where-Object {$_.FeatureName -match "virtualmachineplatform"}

FeatureName : VirtualMachinePlatform
State       : Enabled

Also there were no problems setting up the base machines.

Never saw that before; that seems related to something changed in Windows/VirtualBox/VagrantVirtualBoxProvider. Please try searching/asking for help in the Vagrant repository and let me known what was the solution :-)
