Nested Virtualization
Introduction[edit]
It is possible to run Virtual Machines inside Virtual Machines (VMs). That is called Nested Virtualization. [1]
Qubes[edit]
Running VirtualBox, KVM or Qubes inside Qubes is difficult. Not offically supported by the Qubes developers. It is unrelated to Whonix ™. You can learn more about the current state of things by searching the qubes-devel and qubes-users mailing lists for terms such as VirtualBox, KVM and/or nested virtualization.

VirtualBox inside VirtualBox[edit]
Be sure to change your host key. VirtualBox -> Preferences -> Input -> Host Key. The "outside" and the "inside" Host Key must differ, otherwise you can not leave the VM "inside" anymore.
Using ACPI [2] and IOAPIC [3] [4] for all VM's, speeds up the "inside" VM a lot. These settings are in use for Whonix ™ VMs by default.
VirtualBox does not support VT in VT yet. [5] So the "inside" VM might be slow depending on your host's performance. Inside the "inside" VM, disable VT. VirtualBox -> right click on VM -> Settings -> System -> Acceleration -> uncheck "Enable VT-x/AMD-V"
