...le); > + void (*set_mtf)(struct kvm_vcpu *vcpu, bool enable); MTF is a VMX specific implementation of single-stepping, this should be enable_single_step() or something along those lines. For example, I assume SVM could implement something that is mostly functional via RFLAGS.TF. > void (*cr3_write_exiting)(struct kvm_vcpu *vcpu, bool enable); > bool (*nested_pagefault)(struct kvm_vcpu *vcpu); > bool (*spt_fault)(struct kvm_vcpu *vcpu); > @@ -1628,6 +1629,8 @@ void kvm_arch_msr_intercept(struct kvm_vcpu *vcpu, unsigned int msr, > bool enable); > bool kvm_mmu_nested_pagefault(...

[RFC PATCH v6 00/92] VM introspection
The KVM introspection subsystem provides a facility for applications running on the host or in a separate VM, to control the execution of other VM-s (pause, resume, shutdown), query the state of the vCPUs (GPRs, MSRs etc.), alter the page access bits in the shadow page tables (only for the hardware backed ones, eg. Intel's EPT) and receive notifications when events of interest have taken place
