Oh, ok. I'm sorry, this should have been obvious to me from the start. You need to edit /etc/pam.d/common-session and change the line that's something like session optional pam_cgfs.so -c freezer,memory,name=systemd to add ",cpuset" at the end, i.e. session optional pam_cgfs.so -c freezer,memory,name=systemd,cpuset It has been removed from the default because on systems which do a lot of cpu hotplugging it can be a problem: with the legacy (non-unified) cpuset hierarchy, when you unplug a cpu that is part of /user, it gets removed, but when you re-plug it it does not get re-added. _______________________________________________ lxc-users mailing list [email protected] http://lists.linuxcontainers.org/listinfo/lxc-users
