+Add an IPMI BMC.  This is a simulation of a hardware management

+a watchdog and the ability to reset and power control the system.

+The IPMI slave address to use for the BMC.  The default is 0x20.
+This address is the BMC's address on the I2C network of management
+controllers.  If you don't know what this means, it is safe to ignore
+it.

+Add a connection to an external IPMI BMC simulator.  Instead of
+locally emulating the BMC like the above item, instead connect
+to an external entity that provides the IPMI services.
+
+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.

+Add a KCS IPMI interafce on the ISA bus.  This also adds a
+corresponding ACPI and SMBIOS entries, if appropriate.

+Define the I/O address of the interface.  The default is 0xca0 for KCS.
