xend-config.sxp(5) Xen xend-config.sxp(5)NAMExend-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.
