Turning on nested virtualization Hyper-V

I've been playing around with Hyper-V these past few weeks, and it seems to work rather well (VMware needs to start worrying).

One of the features I've been playing with is nested virtualization. Unlike VMware Workstation where you can select Hyper-V as one of  the install options, in Hyper-V on Windows 10 and Windows 2016, you can turn it on on a per VM basis, with the following command:

Set-VMProcessor -VMName NestHostVM -ExposeVirtualizationExtensions $true

Now you can have a Hyper-V inside your Hyper-V. I'm so hyped about this! <drumroll>

To get a list of which VM's have it turned on, do:

Get-VMProcessor -VMName * |select VMName, ExposeVirtualizationExtensions
