Enable kvm on Ubuntu running on VirtualBox on Windows

Question

I have a computer with an Intel processor (VMX Enabled in the boot menu). I am running Ubuntu Guest on top of it using VirtualBox. I run qemu on top of it to start another guest OS using kvm ( -enable-kvm option).

I get the following error when trying to insert the kvm-intel module:

 FATAL: Error inserting kvm_intel (/lib/modules/2.6.20-ARCH/kernel/drivers/kvm/kvm-intel.ko): Operation not supported 

I checked the vmx flag in the guest OS and I don't see that either

 $ grep vmx /proc/cpuinfo $ 

Is it possible to enable kvm support in the Ubuntu guest operating system so that I can run qemu with kvm support on top of the Ubuntu guest machine?

VMX-function is not transmitted by ̶v̶i̶r̶t̶u̶a̶l̶b̶o̶x̶.̶, and it seems that VirtualBox TEAM themselves do not see that it should be implemented Anytime ̶s̶o̶o̶n̶.̶ See the comments ̶ Https: ̶ / ̶ / ̶w̶w̶w̶.̶v̶i̶r̶t̶u̶a̶l̶b̶o̶x̶.̶o̶r̶g̶ / ̶T̶i̶c̶k̶e̶t̶ / ̶4̶0̶3̶2̶ ̶ ̶
