As a rule, if something isn't possible in dom0 it won't be possible in a 
paravirt domU either.  I'm afraid that's the case here - VirtualBox needs more 
low level control over the CPU than Xen will give it.

You can probably get away with running VirtualBox inside an HVM domU, if you 
have HVM-capable hardware.  If that doesn't work reliably it may be hard to 
fix, though.

Using Qemu without any accelerators (i.e. KVM or kQemu) should also work in 
any domU but it is much slower.

In the future, perhaps somebody will make it possible to virtualise the HVM 
instruction set, then nesting like this will be easier.  For the moment, 
though, that's not possible.

Hope that clears things up.  I think my information is up-to-date...
