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. -- 1.8.0.1.240.ge8a1f5a
