NAME

       xend-config.sxp - Xen daemon configuration file

SYNOPSIS

       /etc/xen/xend-config.sxp

DESCRIPTION

       The xend(1) program requires xend-config.sxp to specify operating
       parameters which determine the behavior of the daemon at runtime.

       The parameters are specified in S-expression format.  See the example
       configuration file in /etc/xen/xend-config.sxp for details.

OPTIONS

       The following lists the daemon configuration parameters:

       logfile
           The location of the file to record runtime log messages.  Defaults
           to /var/log/xen/xend.log.

       loglevel
           Filters out messages below the specified level.  Possible values
           are DEBUG, INFO, WARNING, ERROR, CRITICAL.  Defaults to DEBUG.

       xend-http-server
           A boolean value that tells xend whether or not to start the http
           stream socket management server.  Defaults to no.

       xend-unix-server
           A boolean value that tells xend whether or not to start the unix
           domain socket management server.  This is required for the CLI
           tools to operate.  Defaults to yes.

       xend-relocation-server
           A boolean value that tells xend whether or not to start the
           relocation server.  This is required for cross-machine migrations.
           Defaults to no.

       xend-unix-path
           The location of the unix domain socket the xend-unix-server will
           use to communicate with the management tools.  Defaults to
           /var/lib/xend/xend-socket.

       xend-port
           The port that will be used by the http management server.  Defaults
           to 8000.

       xend-relocation-port
           The port that will be used by the relocation server.  Defaults to
           8002.

       xend-address
           The address to which the http management server will bind.
           Defaults to  which means "all interfaces".

       xend-relocation-address
           The address to which the relocation server will bind.  Defaults to
            which means "all interfaces".

       console-limit
           The kilobyte buffer limit that will be enforced by the console
           server.  This limit is set per-domain, and is needed to prevent a
           single domain from overwhelming the console server with massive
           amounts of data.  Defaults to 1024.

       network-script
           The name of the script in /etc/xen/scripts that will be run to
           setup the networking environment.  This can be any name, but in
           general is either network-bridge or network-route.

       vif-script
           The name of the script in /etc/xen/scripts that will be run to
           setup a virtual interface when it is created or destroyed.  This
           needs to (in general) work in unison with the network-script.

       dom0-min-mem
           This specifies the minimum number of megabytes that will be
           reserved for Domain0.  If this value is positive, Domain0 will be
           automatically ballooned down to this limit to make space for new
           domains.  If this is set to 0, Domain0 will not be automatically
           ballooned.

       dom0-cpus
           This specifies the number of CPUs that Domain0 will be allowed to
           use.  If the value is 0, all available CPUs will be used by
           Domain0.

       enable-dump
           A boolean value that tells xend whether or not core dumps of guest
           domains should be saved when a crash occurs.  Defaults to no.

       external-migration-tool
           The name of an application or script that can handle external
           device migration, such as for example virtual TPM migration. An
           example script is /etc/xen/scripts/external-device-migrate.

EXAMPLES

       An example configuration with relocation enabled for the local network:

        (xend-relocation-server yes)
        (xend-relocation-address 192.0.2.192)
        (network-script network-bridge)
        (vif-script vif-bridge)
        (dom0-min-mem 0)
        (dom0-cpus 0)

CAVEATS

       Note that relocation is currently unsecured and is very dangerous if
       left enabled.  No authentication is performed, and very little sanity
       checking takes place.  Enable at your own risk.
