-The Xen Daemon (\Xend) performs system management functions related to

+your Linux distribution to specify the runlevels at which this script
+should be executed, or manually create symbolic links in the correct
+runlevel directories.

+\subsection{Configuring \Xend\ }
+\Xend\ is written in Python. At startup, it reads its configuration
+information from the file \path{/etc/xen/xend-config.sxp}. The Xen
+installation places an example \texttt{xend-config.sxp} file in the
+\texttt{/etc/xen} subdirectory which should work for most installations.
+See the example configuration file \texttt{xend-debug.sxp} and the
+section 5 man page \texttt{xend-config.sxp} for a full list of
+parameters and more detailed information. Some of the most important
+parameters are discussed below.
+An HTTP interface and a Unix domain socket API are available to
+communicate with \Xend. This allows remote users to pass commands to the
+daemon. By default, \Xend does not start an HTTP server. It does start a
+Unix domain socket management server, as the low level utility
+\texttt{xm} requires it. For support of cross-machine migration, \Xend\
+can start a relocation server. This support is not enabled by default
+for security reasons.
+Note: the example \texttt{xend} configuration file modifies the defaults and
+starts up \Xend\ as an HTTP server as well as a relocation server.
+From the file:
+#(xend-http-server no)
+(xend-http-server yes)
+#(xend-unix-server yes)
+#(xend-relocation-server no)
+(xend-relocation-server yes)
+Comment or uncomment lines in that file to disable or enable features
+that you require.
+Connections from remote hosts are disabled by default:
+# Address xend should listen on for HTTP connections, if xend-http-server is
+# set.
+# Specifying 'localhost' prevents remote connections.
+# Specifying the empty string '' (the default) allows all connections.
+#(xend-address '')
+(xend-address localhost)
+It is recommended that if migration support is not needed, the
+\texttt{xend-relocation-server} parameter value be changed to
+``\texttt{no}'' or commented out.
