+PVEVENT DEVICE
+==============
+
+pvevent device is a simulated ISA device, through which guest panic
+event is sent to qemu, and an qmp event is generated. This allows
+management apps(e.g. libvirt) to be notified and respond to the
+event.
+
+pvevent device is defined with HID "MSFT0001".
+
+To use it, one will have to:
+
+1. add the device by specifying `-device pv-event' in the qemu command
+   line.
+
+2. load pvevent device driver in guest OS.
