There is a community guide for running Qubes in Virtualbox. Have you tried it?

How to install and use Qubes OS inside VirtualBox

A blatant copy-paste of the walkthrough I wrote and posted here. Why bother? Why not? It’s a fun project. Despite the final effect being an unsupported configuration and lacking essential security features for production use, there are still some cases, besides having fun, like testing out the workflow of this system when no supported hardware is present. Or developing software for Domain-0, which is better suited for testing on a living system, rather than with mocks. Or learning some…

But it is a pretty janky configuration. I dig it though. It would be really nice to have nested virtualization in Qubes.
