Yes, that sounds like an inherently unstable configuration. I don't
know anything about how VBox operates internally, but whatever pagetable
management scheme they're using will quite likely not work under Xen
without a lot of care. The best we can do in that case is try to make
sure that VBox doesn't attempt to come up.
If they don't rely on VT/SVM, then it may work from within a Xen hvm
domain, but I don't know what benefit that would have. What were you
trying to achieve by running VBox in dom0?
