Hi there, When I testing EPT violation VMEXIT, I get some confusions in bit 7&8 in "Exit Qualification for EPT Violations" (Table 27-7 in SDM). Bit 7 means "Set if the guest linear-address field is valid." In which occasion will bit 7 clear? I don't quite understand the following statements in SDM "The guest linear-address field is valid for all EPT violations except those resulting from an attempt to load the guest PDPTEs as part of the execution of the MOV CR instruction." Bit 8 means the causes of EPT violation. But I don't understand what it is means when set and clear. I always get the exit qualification with this bit set, how to design a violation with this bit clear?
