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.
