You need to either echo 1 > /sys/fs/cgroup/cpuset/cgroup.clone_children, or else manually cp cpuset.cpus and cpuset.mems from the parent to the child cgroup. Otherwise you cannot place a task into the cgroup. > Also, what is handling creating these initial per-user cgroups on > Ubuntu?

Before that you did have to do it by hand. -serge _______________________________________________ lxc-devel mailing list lxc-devel@lists.linuxcontainers.org http://lists.linuxcontainers.org/listinfo/lxc-devel
