lxc-cgroup — manage the control group associated with a container

Synopsis

lxc-cgroup {-n name} {state-object} [value]

Description

lxc-cgroup gets or sets the value of a state-object (e.g., 'cpuset.cpus') in the container's cgroup for the corresponding subsystem (e.g., 'cpuset'). If no [value] is specified, the current value of the state-object is displayed; otherwise it is set.

Note that lxc-cgroup does not check that the state-object is valid for the running kernel, or that the corresponding subsystem is contained in any mounted cgroup hierarchy.

Options

state-object
Specify the state object name.
[value]
Specify the value to assign to the state object.

Common Options

These options are common to most of lxc commands.

-?, -h, --help

-q, --quiet

-P, --lxcpath=PATH
Use an alternate container path. The default is /var/lib/lxc.
-o, --logfile=FILE
Output to an alternate log FILE. The default is no log.
-l, --logpriority=LEVEL

Set log priority to LEVEL. The default log priority is ERROR. Possible values are : FATAL, CRIT, WARN, ERROR, NOTICE, INFO, DEBUG.

Note that this option is setting the priority of the events log in the alternate log file. It do not have effect on the ERROR events log on stderr.

-n, --name=NAME
Use container identifier NAME. The container identifier format is an alphanumeric string.
--rcfile=FILE

Specify the configuration file to configure the virtualization and isolation functionalities for the container.

This configuration file if present will be used even if there is already a configuration file present in the previously created container (via lxc-create).

--version
Show the version number.

Examples

lxc-cgroup -n foo devices.list
display the allowed devices to be used.
lxc-cgroup -n foo cpuset.cpus "0,3"
assign the processors 0 and 3 to the container.

Diagnostic
