From: Corey Minyard <cminyard@xxxxxxxxxx>
Add the basic IPMI types and infrastructure to QEMU. Low-level
interfaces and simulation interfaces will register with this; it's
kind of the go-between to tie them together.

+Set up an IPMI interface. The physical interface may either be
+KCS or BT, the default is KCS. Two options are available for
+simulation of the IPMI BMC. If @code{local} is specified, then a
+minimal internal BMC is used. This BMC is basically useful as a
+watchdog timer and for fooling a system into thinking IPMI is there.
+
+If @var{dev} is specified (see the serial section above for details on
+what can be specified for @var{dev}) then a connection to an external IPMI
+simulator is made. This interface has the ability to do power control
+and reset, so it can do the normal IPMI types of things required.
+
+The OpenIPMI project's lanserv simulator is capable of providing
+this interface. It is also capable of an IPMI LAN interface, and
+you can do power control (the lanserv simulator is capable of starting
+a VM, too) and reset of a virtual machine over a standard remote LAN
+interface. For details on this, see OpenIPMI.
+
+The remote connection to a LAN interface will reconnect if disconnected,
+so if a remote BMC fails and restarts, it will still be usable.
+
+For instance, to connect to an external interface on the local machine
+port 9002 with a BT physical interface, do the following:
+@table @code
+@item -ipmi bt,tcp:localhost:9002
+@end table
+
+Use @code{-ipmi none} to disable IPMI.
