Abstract
A virtual machine manager facilitates selective code integrity enforcement. A virtual machine manager (or other higher privileged entity) can verify the integrity of code in memory pages, and a virtual processor running in kernel mode executes the code on a memory page only if the virtual machine manager (or other higher privileged entity) has verified the code integrity of that code. However, the virtual machine manager need not verify the integrity of code in memory pages when the virtual processor is running in user mode. Rather, an operating system running on the virtual processor can apply any of a variety of policies (e.g., optionally perform any of a variety of different checks or verifications of the code) to determine whether the code can be executed in user mode.
