Unfortunately, it doesn't work yet. linux-image linux-image-4.5.0-040500rc4-generic systemd 229-1ubuntu2 lxc 1.1.5-0ubuntu0.15.10.3 starting a container gives: lxc-start 1455712091.086 DEBUG lxc_console - console.c:lxc_console_peer_default:536 - no console peer lxc-start 1455712091.092 INFO lxc_monitor - monitor.c:lxc_monitor_sock_name:178 - using monitor sock name lxc/1139bd77ce7a3a6c//home/bas/.local/share/lxc lxc-start 1455712091.132 INFO lxc_start - start.c:lxc_init:474 - 'aansluitform-deploy' is initialized lxc-start 1455712091.132 DEBUG lxc_start - start.c:__lxc_start:1186 - Not dropping cap_sys_boot or watching utmp lxc-start 1455712091.133 INFO lxc_start - start.c:resolve_clone_flags:883 - Cloning a new user namespace lxc-start 1455712091.133 INFO lxc_cgroup - cgroup.c:cgroup_init:65 - cgroup driver cgmanager initing for aansluitform-deploy lxc-start 1455712091.138 ERROR lxc_cgmanager - cgmanager.c:lxc_cgmanager_enter:698 - call to cgmanager_move_pid_sync failed: invalid request lxc-start 1455712091.138 ERROR lxc_start - start.c:__lxc_start:1213 - failed to spawn 'aansluitform-deploy' lxc-start 1455712091.163 WARN lxc_commands - commands.c:lxc_cmd_rsp_recv:172 - command get_init_pid failed to receive response lxc-start 1455712091.164 WARN lxc_cgmanager - cgmanager.c:cgm_get:994 - do_cgm_get exited with error lxc-start 1455712096.169 ERROR lxc_start_ui - lxc_start.c:main:344 - The container failed to start. -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to lxc in Ubuntu. https://bugs.launchpad.net/bugs/1533833 Title: unprivileged lxc containers won't start, need to put sessions into "pids" cgroup controller To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1533833/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
