Hyper-V cannot be installed: The processor does not have the required virtualization capabilities

Open Powershell in your virtual machine and run the following two commands and then restart your VM.

Enable-WindowsOptionalFeature –Online -FeatureName Microsoft-Hyper-V –All -NoRestart

Install-WindowsFeature RSAT-Hyper-V-Tools -IncludeAllSubFeature

Why the hell does this work but not doing it the standard way XD

Got dam computers why you weird.

Hello there, it worked but there are no Components running in service for creating  VM in Hyper-V, that it not help well. That is frustrating :(

It keeps saying that its spelled wrong but I've typed it exactly as you have it.

The script worked, but the role still fails because You can't run Hyper-V within a virtualBox VM.  See below:

- My physical box is a Windows 10 64 bit host with an Intel(R) Core(TM) i7-6700 CPU.
- Inside the host I installed VirtualBox 6.1.18-142142
- Inside VirtualBox I installed a Windows Server 2019 guest VM
- When I try to enable the Hyper-v role in the guest Windows Server 2019 VM I get the eror "Hyper-v cannot be installed: The processor does not support second level address translation (SLAT)"
- On the same physical box I installed VMware Workstation 15 Player
- Inside VMware Workstation Player I installed a Windows Server 2019 guest VM
- Inside the guest Windows Server 2019 VM I can enable the Hyper-v role and I can create and run guest VMs
That means, in my opinion, that my HW supports nested virtualization while my VirtualBox does not.

Thanks Ryan Genius ;) it's been 3weeks looking for solution :)
