hmm, how can I use cfsng instead of cgfs? I simply use the newest cgmanager and start it the usual way: /usr/local/sbin/cgmanager --daemon -m name=systemd And $ cat /proc/self/cgroup 14:name=systemd:/ 13:pids:/ 12:perf_event:/ 11:net_prio:/ 10:net_cls:/ 9:memory:/ 8:hugetlb:/ 7:freezer:/ 6:devices:/ 5:debug:/ 4:cpuset:/ 3:cpuacct:/ 2:cpu:/ 1:blkio:/ $ mount |grep cgroup cgroup on /sys/fs/cgroup type tmpfs (rw,relatime,size=12k,mode=755) On older systems, where lxc-attach works, I see also: cgmfs 100 0 100 0% /run/cgmanager/fs Can this cause the problem? I don't see it on the newer system... (I have no idea, where this mount is coming from...) > It might help if you set the lxc.cgroup.use in your personal > lxc.system.conf (~/.config/lxc/lxc.conf) to only include the cgroups > your container needs - just freezer is the bare minimum. That might > get your container running without switching to cgfsng. hmm, you mean ~/.config/lxc/default.conf? I added it: ~$ grep lxc.cgroup.use .config/lxc/default.conf lxc.cgroup.use = freezer But it doesn't change anything, even if I add it to ~/.local/share/lxc/lxc-stretch/config It's all a little bit strange. As user root, I can use lxc-attach with setting the right Path via option -P. But it does not work with the unpriviliged user, who started the container... For me it is not a major problem, since I can attach as user root. And if the network is up and running, I can manage it via ssh. But I am a little bit irritated. The old system works with cgmanager 0.33 lxc 1.0.7 The new system uses the newest versions: cgmanager 0.41 lxc 2.0.8 Best regards Dirk -- +----------------------------------------------------------------------+ | Dr. Dirk Geschke / Plankensteinweg 61 / 85435 Erding | | Telefon: 08122-559448 / Mobil: 0176-96906350 / Fax: 08122-9818106 | | d...@geschke-online.de / d...@lug-erding.de / kont...@lug-erding.de | +----------------------------------------------------------------------+ _______________________________________________ lxc-users mailing list lxc-users@lists.linuxcontainers.org http://lists.linuxcontainers.org/listinfo/lxc-users
