/etc/xen/xl.conf - XL Global/Host Configuration
The xl.conf file allows configuration of hostwide xl
toolstack
options.
For details of per-domain configuration options please see xl.cfg(5).
The config file consists of a series of KEY=VALUE
pairs.
A value VALUE
is one of:
A string, surrounded by either single or double quotes.
A number, in either decimal, octal (using a 0
prefix) or
hexadecimal (using an 0x
prefix).
A NUMBER
interpreted as False
(0
) or True
(any other
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.
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
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
Sets the path to the lock file used by xl to serialise certain operations (primarily domain creation).
Default: /var/lock/xl
Configures the default hotplug script used by virtual network devices.
Default: /etc/xen/scripts/vif-bridge
Configures the default bridge to set for virtual network devices.
Default: xenbr0
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
Configures the name of the first block device to be used for temporary block device allocations by the toolstack. The default choice is "xvda".
