Hi, --- My system --- Kernel version: 3.13.0-29-generic Release: 14.04 Platform: ec2 LXC: 1.0.5 ---
I cannot start an unprivileged LXC container on Ubuntu 14.04 after installing LXC and configuring unprivileged container access, as per https://www.stgraber.org/2014/01/17/lxc-1-0-unprivileged-containers/. However, after restarting the instance, unprivileged containers can be created. The error message, on "lxc-start -n cn_name", is as follows: lxc_container: call to cgmanager_create_sync failed: invalid request lxc_container: Failed to create hugetlb:p1 lxc_container: Error creating cgroup hugetlb:p1 lxc_container: failed creating cgroups lxc_container: failed to spawn 'p1' lxc_container: The container failed to start. lxc_container: Additional information can be obtained by setting the --logfile and --log-priority options. This is the same issue, as found here: https://lists.linuxcontainers.org/pipermail/lxc-users/2014-July/007413.html I've tried things suggested (restart cgmanager etc.) in this thread, with no result. The only additional info I've found is a discrepancy of the contents of the "/proc/self/cgroup" file before and after restart of the instance. Before: 11:hugetlb:/ 10:perf_event:/ 9:blkio:/ 8:freezer:/ 7:devices:/ 6:memory:/ 5:cpuacct:/ 4:cpu:/ 3:cpuset:/ 2:name=systemd:/user/1000.user/1.session After: 11:hugetlb:/user/1000.user/1.session 10:perf_event:/user/1000.user/1.session 9:blkio:/user/1000.user/1.session 8:freezer:/user/1000.user/1.session 7:devices:/user/1000.user/1.session 6:memory:/user/1000.user/1.session 5:cpuacct:/user/1000.user/1.session 4:cpu:/user/1000.user/1.session 3:cpuset:/user/1000.user/1.session 2:name=systemd:/user/1000.user/1.session It looks like required cgroups have not been delegated? I don't have a deep understanding of cgroups, or of how cgroups and LXC interact, so the answer may be obvious to someone else. Thanks in advance for your time, Justin
