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.

       device-create-timeout
           Integer value that tells xend how long it should wait for a new device to be created.
           Defaults to 100.

       device-destroy-timeout
           Integer value that tells xend how long it should wait for a device to be destroyed.
           Defaults to 100.

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.
