Nested Virtualization

From Whonix


It is possible to run Virtual Machines inside Virtual Machines (VMs). That is called Nested Virtualization. [1]


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"
