Can we emulate OVM inside VirtualBox ? #2

In the previous posting the quick answer was "no". However... the correct answer may be "yes".

In the Oracle VM Hand-on Labs, there is a download where the issue is solved. As it can be done in VMware, it should be possible in VirtualBox. The Hands-on VM is pre-build and doesn't explain how, nor the documentation (pdf). But I think the answer lies in the para-virtualization interface:



I am downloading the image to find out :)

Can we emulate OVM inside VirtualBox ?

Earlier I tried to run OVM inside VMWare Fusion, but I never was sure if we could run OVM inside VirtualBox.

I attempted this, and the answer is NO, at least not with VirtualBox 4. We can install OVS and OVMM, but once we start a machine, it appears the required instructionset is not available in VirtualBox.

Even though hardware virtualization is available to the server:
