NAME

       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

       --usage
              Give the usage message

       -q, --quiet
              mute on

       -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

              CRIT, WARN, ERROR, NOTICE, INFO, DEBUG, TRACE.

              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.

       --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.
