When developing projects locally, there may be a need to enable virtualization in a virtual machine environment. This can be done by enabling the nested virtualization feature in Hyper-V through PowerShell commands.

When developing projects locally, sometimes we encounter the need to enable virtualization in a virtual machine environment. Alternatively, if we have set up a PVE (Proxmox Virtual Environment) using a virtual machine, we may need to create virtual instances within PVE (although this may not be meaningful).

In such cases, we need to enable the nested virtualization feature of Hyper-V. This feature cannot be directly enabled in the Hyper-V application and requires setting it in the PowerShell command line.

Open the terminal as an administrator.
Get the name of the virtual machine:

get-vm

Enable nested virtualization:

Set-VMProcessor [hostname] -ExposeVirtualizationExtensions $true

Check the enabled status:

Get-VMProcessor [hostname] | fl

That's it.
