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


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


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.


Specify the state object name.
Specify the value to assign to the state object.
