Protected memory view for nested page table access by virtual machine guests
Abstract:
Generally, this disclosure provides systems, methods and computer readable media for a protected memory view in a virtual machine (VM) environment enabling nested page table access by trusted guest software outside of VMX root mode. The system may include an editor module configured to provide access to a nested page table structure, by operating system (OS) kernel components and by user space applications within a guest of the VM, wherein the nested page table structure is associated with one of the protected memory views. The system may also include a page handling processor configured to secure that access by maintaining security information in the nested page table structure.
