+If a chardev is not specified, the IPMI driver uses a built-in baseboard
+management controller (BMC) simulator.  It provides a basic BMC with a
+watchdog timer and associated sensor.
+If a chardev is specified, A connection is made to an external BMC
+simulator.  If you do this, it is strongly recommended that you use
+the "reconnect=" chardev option to reconnect to the simulator if the
+connection is lost.  Note that if this is not used carefully, it can
+be a security issue, as the interface has the ability to send resets,
+NMIs, and power off the VM.  It's best if QEMU makes a connection to
+an external simulator running on a secure port on localhost, so
+neither the simulator nor QEMU is exposed to any outside network.
+See the "lanserv/README.vm" file in the OpenIPMI library for more
+details on the external interface.
