+KVM PV EVENT
+============
+
+kvm pv event allows guest OS to notify host OS of some events, for
+example, guest panic. Currently, there is one event supported, that
+is, guest panic. More events can be added later.
+
+By default, kvm pv event is disabled. In order to enable it, you have
+to specify enable_pv_event=on for -machine command line option, along
+with -global kvm_pv_event.panicked_action to specify the action taken
+when panic event has occurred. Aviable panic actions are: "none",
+"pause", "poweroff" and "reset". Following is example:
+
+ qemu-system-x86_64 -enable-kvm -machine pc-0.12,enable_pv_event=on \
+ -global kvm_pv_event.panicked_action=pause <other options>
+
+kvm pv event needs kvm support.
