Abstract
Embodiments of systems, apparatuses, and methods for determining if an instruction of a virtual machine is allowed to modify a protected memory region are described. In some embodiments, a system detects an indication of an attempt by the instruction to write to the protected memory region. In addition, the system determines if the instruction is allowed to write to the protected memory region based on a starting address and data length of the instruction. Furthermore, if the instruction is allowed to write to the protected memory region, the system updates the protected memory region with the instruction results.
