And this is where things start to get funny.... After more testing I can see that if you use "lxc-attach" you get the right cgroups. But the process started inside the container via the container init are not getting the right cgroups. See the following example. Just rebooted machine: # pstree -pa systemd,1 │ ├─ [ unrelated process .... ] | ├─lxc-autostart,670 -g onboot, │ └─systemd,718 │ ├─agetty,1001 --noclear tty4 linux │ ├─agetty,1002 --noclear tty1 linux │ ├─agetty,1003 --noclear tty3 linux │ ├─agetty,1004 --noclear tty2 linux │ ├─agetty,1005 --noclear --keep-baud console 115200 38400 9600 vt102 │ └─systemd-journal,934 | ├─ [ unrelated process .... ] # cat /proc/718/cgroup 9:perf_event:/lxc/lxctest2 8:blkio:/ 7:net_cls,net_prio:/lxc/lxctest2 6:freezer:/lxc/lxctest2 5:devices:/ 4:memory:/ 3:cpu,cpuacct:/ 2:cpuset:/lxc/lxctest2 1:name=systemd:/system.slice/lxc.service # lxc-attach -n lxctest2 -- cat /proc/1/cgroup 9:perf_event:/lxc/lxctest2 8:blkio:/ 7:net_cls,net_prio:/lxc/lxctest2 6:freezer:/lxc/lxctest2 5:devices:/ 4:memory:/ 3:cpu,cpuacct:/ 2:cpuset:/lxc/lxctest2 1:name=systemd:/system.slice/lxc.service # lxc-attach -n lxctest2 -- cat /proc/self/cgroup 9:perf_event:/lxc/lxctest2 8:blkio:/lxc/lxctest2 7:net_cls,net_prio:/lxc/lxctest2 6:freezer:/lxc/lxctest2 5:devices:/lxc/lxctest2 4:memory:/lxc/lxctest2 3:cpu,cpuacct:/lxc/lxctest2 2:cpuset:/lxc/lxctest2 1:name=systemd:/user.slice/user-0.slice/session-1.scope As you can see, it is only working for the process that fork from the lxc-attach point, but not for the process started by the container init. I tried replacing systemd with sysvinit in the container. Same result Can you reproduce this?
