Hi Mathieu,

It's difficult to review your patches because they aren't inlined.

At any rate, this patches are unusable with SVM.  They try to execute VT 
instructions unconditionally.  For instance, you changed:

>
> -    KVMTRACE_1D(INTR, vcpu, vmcs_read32(VM_EXIT_INTR_INFO), handler);
> +    trace_kvm_intr(vcpu);

Which lived in VT-specific code (vmx.c)

To:

quoted text

> +{
> +    kvm_add_trace(KVM_TRC_INTR, vcpu, 1,
> +        (u32 []){ vmcs_read32(VM_EXIT_INTR_INFO) });
> +}
> +

Which lives in common code (kvm_trace.c).  But vmcs_read32() is 
VT-specific and should not be used in common code so this motion is 
wrong.  Why not just pass more arguments to probe_kvm_intr()?  Then your 
first two patches can be dropped completely.

Anthony Liguori
