+Currently, only MSRs within the following two ranges are supported. Trying

[RFC PATCH v6 16/92] kvm: introspection: handle events and event replies
...@ in almost all cases, it must reply with: continue, retry, crash, etc.
* -KVM_EINVAL - padding is not zero
* -KVM_EPERM - the access is restricted by the host
+Events
+======
+
+All vCPU events are sent using the *KVMI_EVENT* message id. No event
+will be sent unless explicitly enabled with a *KVMI_CONTROL_EVENTS*
+or a *KVMI_CONTROL_VM_EVENTS* command or requested, as it is the case
+with the *KVMI_EVENT_PAUSE_VCPU* event (see **KVMI_PAUSE_VCPU**).
+
+There is one VM event, *KVMI_EVENT_UNHOOK*, which doesn't have a reply,
+but shares the kvmi_event structure, for consistency with the vCPU events.
