Abstract:
A system, methods, and apparatus for using hypervisor trapping for protection against interrupts in virtual machine functions are disclosed. A system includes memory, one or more physical processors, a virtual machine executing on the one or more physical processors, and a hypervisor executing on the one or more physical processors. The hypervisor reads an interrupt data structure on the virtual machine. The hypervisor determines whether the interrupt data structure points to an alternate page view. Responsive to determining that the interrupt data structure points to an alternate page view, the hypervisor disables a virtual machine function.

Claim (Index 20):
A computer-readable non-transitory storage medium comprising executable instructions of restricting access to memory resources by a virtual machine, a host operating system, and a guest operating system that, when executed by a computer system, cause the computer system to:\n activate a trap to a hypervisor prior to an execution of an instruction that loads an interrupt data structure on a virtual machine, wherein the virtual machine executes with a default page view stored in a default page table; read the interrupt data structure to determine that the interrupt data structure points to an alternate page view stored in an alternate page table, which is different from the default page view and the alternate page view includes a reference to a memory location outside of a memory location of a virtual machine function; and disable the virtual machine function.
