I'm wondering if this comment in mmu.c:init_kvm_nested_mmu is correct (at least in the context of Nested EPT):
4055 /* 4056 * Note that arch.mmu.gva_to_gpa translates l2_gva to l1_gpa. The 4057 * translation of l2_gpa to l1_gpa addresses is done using the 4058 * arch.nested_mmu.gva_to_gpa function. Basically the gva_to_gpa 4059 * functions between mmu and nested_mmu are swapped. 4060 */ nested_mmu.get_cr3 gets set to get_cr3, which I believe will return L2's cr3. In vmx.c:nested_ept_init_mmu_context, mmu.get_cr3 is set to nested_ept_get_cr3, which should be the root of EPT12. Given these get_cr3 functions, shouldn't nested_mmu.gva_to_gpa translate l2_gva->l2_gpa and mmu.gva_to_gpa translate l2_gpa->l1_gpa? -- To unsubscribe from this list: send the line "unsubscribe kvm" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
