lxc-cgroup(1)

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

SYNOPSIS
\FClxc-cgroup\F[]
{-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.

\FC[value]\F[]
    Specify the value to assign to the state object.

COMMON OPTIONS

\FC-?, -h, --help\F[]
    Print a longer usage message than normal.

\FC--usage\F[]
    Give the usage message

\FC-q, --quiet\F[]
    mute on

\FC-P, --lxcpath=\F[]PATH
    Use an alternate container path. The default is /var/lib/lxc.

\FC-o, --logfile=\F[]FILE
    Output to an alternate log FILE. The default is no log.

\FC-l, --logpriority=\F[]LEVEL
    Set log priority to LEVEL. The default log priority is \FCERROR\F[]. Possible values are : \FCFATAL\F[], \FCALERT\F[], \FCCRIT\F[], \FCWARN\F[], \FCERROR\F[], \FCNOTICE\F[], \FCINFO\F[], \FCDEBUG\F[], \FCTRACE\F[].

    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.

\FC-n, --name=\F[]NAME
    Use container identifier NAME. The container identifier format is an alphanumeric string.

\FC--rcfile=\F[]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).

\FC--version\F[]
    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

The container was not found
