Nested virtualization - can't change settings of a new machine inside the Whonix Workstation.

VirtualBox

Hi, so I’m trying to run a nested virtualization (mother VM version 6.1) with a Windows 7 32-bit ran inside a Whonix Workstation (Whonix-XFCE-15.0.0.9.4) and after I’ve created a new machine, the ‘OK’ to change any settings is grayed out. VM version in the Whonix Workstation is 6.1 as well.

I suggest to learn nested virtualization without Whonix involved first. Free Support for Whonix ™ applies.

Useful response Patrick, glad you took your time to post that.

Issue solved, for anyone having the same issue -

  1. Nested virtualization had to be enabled on the “host” VM - that’s the Enabled Nested VT-x/AMD-V setting on the Processor tab

  2. With an Intel processor, you’ll need to force the setting (on Windows) with opening CMD in the VirtualBox install folder and use
    VBoxManage modifyvm YourVirtualBoxName --nested-hw-virt

Glad it worked for you.

Made some changes to that wiki page:
Nested Virtualization: Difference between revisions - Whonix

I can confirm I managed to run a nested VirtualBox VM
(A Whonix-Workstation VM inside a Whonix-Workstation VM - just for testing. Not for serious use.)
