VirtualBox inside a VM is not going to work, at least not with x64. It might work with x86 (32b).
Virtualization for x64 generally requires virtualization extensions (VT-x or so), but they aren't available inside a Qubes VM. Maybe some patches can add support for it (look for “nested HVM” or “nested virtualization”), at the cost of additional complexity and thus larger attack surface. It reportedly used to be impossible to implement x64 virtualization without those extensions. It might be possible now, but I haven't seen it being implemented. Virtualization for x86 (32-bit) guests might work even without virtualization extensions. I haven't tried it, though. If course, emulation (QEMU, DosBox, …) will work, but it is going to be slow.
