[vbox-dev] Possible bug in VB

[Sander van Leeuwen]

Thanks for the link. I've found and fixed the problem. It's an edge case 
where the guest writes to a non-present guest page
in the same region our hypervisor is located. That caused a #PF storm 
inside the guest, because the hypervisor range conflict
check was performed too late.
