ns_cgroup has been removed a few years ago. https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a77aea92010acf54ad785047234418d5d68772e2 commit a77aea92010acf54ad785047234418d5d68772e2 Author: Daniel Lezcano <daniel.lezc...@free.fr> Date: Thu May 26 16:25:23 2011 -0700 cgroup: remove the ns_cgroup The ns_cgroup is an annoying cgroup at the namespace / cgroup frontier and leads to some problems: * cgroup creation is out-of-control * cgroup name can conflict when pids are looping * it is not possible to have a single process handling a lot of namespaces without falling in a exponential creation time * we may want to create a namespace without creating a cgroup The ns_cgroup was replaced by a compatibility flag 'clone_children', where a newly created cgroup will copy the parent cgroup values. The userspace has to manually create a cgroup and add a task to the 'tasks' file. > > Best > DavidS > > > On Sun, Mar 31, 2013 at 10:18 AM, David Shwatrz <dshwa...@gmail.com> wrote: > > Hi, > > This is Fedora 18: > > > > uname -r > > 3.8.4-202.fc18.x86_64 > > > > cat /proc/cgroups > > #subsys_name hierarchy num_cgroups enabled > > cpuset 2 1 1 > > cpu 3 37 1 > > cpuacct 3 37 1 > > memory 4 1 1 > > devices 5 1 1 > > freezer 6 1 1 > > net_cls 7 1 1 > > blkio 8 1 1 > > perf_event 9 1 1 > > > > DS > > > > On Sun, Mar 31, 2013 at 7:55 AM, Corey Carpenter <fruitwe...@gmail.com> > > wrote: > >> What is your host OS and Kernel version? > >> > >> Does /proc/cgroup exists, what are the contents? > >> > >> ...
