Abstract: A computing system includes virtualization software including a guest operating system (OS). A method maintains, by the virtualization software layer, a first shadow page table for use in a kernel mode and a second shadow page table for use in a user mode. The virtualization software switches between using the first shadow page table and the second shadow page table when the guest OS switches between operating in the kernel mode and the user mode.
