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-18.104.22.168.4) 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. https://www.whonix.org/wiki/Free_Support_Principle applies.
Useful response Patrick, glad you took your time to post that.
Issue solved, for anyone having the same issue -
Nested virtualization had to be enabled on the “host” VM - that’s the Enabled Nested VT-x/AMD-V setting on the Processor tab
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:
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.)
