/etc/xen/xl.conf - XL Global/Host Configuration
DESCRIPTION
The xl.conf file allows configuration of hostwide "xl" toolstack
options.
For details of per-domain configuration options please see xl.cfg(5).
SYNTAX
The config file consists of a series of "KEY=VALUE" pairs.
A value "VALUE" is one of:
"STRING"
A string, surrounded by either single or double quotes.
NUMBER
A number, in either decimal, octal (using a 0 prefix) or
hexadecimal (using an "0x" prefix).
BOOLEAN
A "NUMBER" interpreted as "False" (0) or "True" (any other value).
[ VALUE, VALUE, ... ]
A list of "VALUES" of the above types. Lists are homogeneous and
are not nested.
The semantics of each "KEY" defines which form of "VALUE" is required.
OPTIONS
autoballoon=BOOLEAN
If disabled then "xl" will not attempt to reduce the amount of
memory assigned to domain 0 in order to create free memory when
starting a new domain. You are strongly recommended to set this to
0 ("False") if you use the "dom0_mem" hypervisor command line to
reduce the amount of memory given to domain 0 by default.
Default: 1
run_hotplug_scripts=BOOLEAN
If disabled hotplug scripts will be called from udev, as it used to
be in the previous releases. With the default option, hotplug
scripts will be launched by xl directly.
Default: 1
lockfile="PATH"
Sets the path to the lock file used by xl to serialise certain
operations (primarily domain creation).
Default: "/var/lock/xl"
vifscript="PATH"
Configures the default hotplug script used by virtual network
devices.
Default: "/etc/xen/scripts/vif-bridge"
defaultbridge="NAME"
Configures the default bridge to set for virtual network devices.
Default: "xenbr0"
output_format="json|sxp"
Configures the default output format used by xl when printing
"machine readable" information. The default is to use the "JSON"
<http://www.json.org/> syntax. However for compatibility with the
previous "xm" toolstack this can be configured to use the old "SXP"
(S-Expression-like) syntax instead.
Default: "json"
blkdev_start="NAME"
Configures the name of the first block device to be used for
temporary block device allocations by the toolstack. The default
choice is "xvda".
