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.
