Nested hardware virtualization is a very interesting topic that AFAIK noone has yet to address. The VT instruction set would have to be emulated of course. It's a bit easier with VT I suspect b/c you can more easily trap things like vmwrite to ensure the guest isn't building a malicious VMCS. It would incur some overhead in already sensitive places (since vmlaunch/vmresume will trap). I think it could be done in such a way though that any level of nesting will have a fixed overhead. An analysis of this would make a pretty interesting paper IMHO.
