Enables or disables DEA key wrapping support on s390-ccw hosts. This feature
controls whether DEA wrapping keys will be created to allow
execution of DEA cryptographic functions. The default is on.

+Some drivers are:
+@item -device ipmi-bmc-sim,id=@var{id}[,slave_addr=@var{val}]
+
+Add an IPMI BMC. This is a simulation of a hardware management
+interface processor that normally sits on a system. It provides
+a watchdog and the ability to reset and power control the system.
+You need to connect this to an IPMI interface to make it useful
+
+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.
+
+@item -device ipmi-bmc-extern,id=@var{id},chardev=@var{id}[,slave_addr=@var{val}]
+
+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.
+
+@item -device isa-ipmi-kcs,bmc=@var{id}[,ioport=@var{val}][,irq=@var{val}]
+
+Add a KCS IPMI interafce on the ISA bus. This also adds a
+corresponding ACPI and SMBIOS entries, if appropriate.
+
+@table @option
+@item bmc=@var{id}
+The BMC to connect to, one of ipmi-bmc-sim or ipmi-bmc-extern above.
+@item ioport=@var{val}
+Define the I/O address of the interface. The default is 0xca0 for KCS.
+@item irq=@var{val}
+Define the interrupt to use. The default is 5. To disable interrupts,
+set this to 0.
+@end table
+
+@item -device isa-ipmi-bt,bmc=@var{id}[,ioport=@var{val}][,irq=@var{val}]
+
+Like the KCS interface, but defines a BT interface. The default port is
+0xe4 and the default interrupt is 5.

The key sequence of @key{Control-a} and @key{c} will rotate the input focus
between attached front-ends. Specify @option{mux=on} to enable this mode.
-Options to each backend are described below.
+Every backend supports the @option{logfile} option, which supplies the path
+to a file to record all data transmitted via the backend. The @option{logappend}
+option controls whether the log file will be truncated or appended to when
+opened.
+
+Further options to each backend are described below.
@item -chardev null ,id=@var{id}
A void device. This device will not emit any data, and will drop any data it
receives. The null backend does not take any options.
-@item -chardev socket ,id=@var{id} [@var{TCP options} or @var{unix options}] [,server] [,nowait] [,telnet] [,reconnect=@var{seconds}]
+@item -chardev socket ,id=@var{id} [@var{TCP options} or @var{unix options}] [,server] [,nowait] [,telnet] [,reconnect=@var{seconds}] [,tls-creds=@var{id}]
Create a two-way stream socket, which can be either a TCP or a unix socket. A
unix socket will be created if @option{path} is specified. Behaviour is
the remote end goes away. qemu will delay this many seconds and then attempt
to reconnect. Zero disables reconnecting, and is the default.
+@option{tls-creds} requests enablement of the TLS protocol for encryption,
+and specifies the id of the TLS credentials to use for the handshake. The
+credentials must be previously created with the @option{-object tls-creds}
+argument.
+
TCP and unix socket options are given below:
