1. A computing device comprising:
logic to receive permission information for guest physical mapping prior to utilization of paged memory by an Operating System (OS) based on the guest physical mapping; and logic to examine an OS Global Partition Table (GPT) to determine whether an expected Guest Virtual Address (GVA) is present in the GPT in response to a mismatch between a fault GVA and the expected GVA. |
