Using Virtualbox and Hyper-V on the same system

It's always a challenge to use Virtualbox and MS Hyper-V on the same system, as the CPU's virtualization features are locked by Hyper-V at boot time.

There isn't a way that I know of to use both simultaneously, but at least there is a way to easily enable/disable hyper-v to allow virtualbox access.  Unfortunately it does require a reboot:

Disabling Hyper-V:

Open an elevated command prompt and execute:

bcdedit /set hypervisorlaunchtype off

Enabling Hyper-V:

Open an elevated command prompt and execute:

bcdedit /set hypervisorlaunchtype auto
