Hi, I'm running Fedora 16 and I'm trying to run an LXC container. I think that my problem comes from how Fedora mount the different cgroup subsystems. Each subsystem is mounted on its own file system:
tmpfs on /sys/fs/cgroup type tmpfs (rw,nosuid,nodev,noexec,relatime,seclabel,mode=755) cgroup on /sys/fs/cgroup/systemd type cgroup (rw,nosuid,nodev,noexec,relatime,release_agent=/lib/systemd/systemd-cgroups-agent,clone_children,name=systemd) cgroup on /sys/fs/cgroup/cpuset type cgroup (rw,nosuid,nodev,noexec,relatime,cpuset) cgroup on /sys/fs/cgroup/cpu,cpuacct type cgroup (rw,nosuid,nodev,noexec,relatime,cpuacct,cpu) cgroup on /sys/fs/cgroup/memory type cgroup (rw,nosuid,nodev,noexec,relatime,memory) cgroup on /sys/fs/cgroup/devices type cgroup (rw,nosuid,nodev,noexec,relatime,devices) cgroup on /sys/fs/cgroup/freezer type cgroup (rw,nosuid,nodev,noexec,relatime,freezer) cgroup on /sys/fs/cgroup/net_cls type cgroup (rw,nosuid,nodev,noexec,relatime,net_cls) cgroup on /sys/fs/cgroup/blkio type cgroup (rw,nosuid,nodev,noexec,relatime,blkio) cgroup on /sys/fs/cgroup/perf_event type cgroup (rw,nosuid,nodev,noexec,relatime,perf_event) When I try to start my container, here is what I get: # lxc-start -f config -n generic lxc-start: open /sys/fs/cgroup/systemd/generic/devices.deny : No such file or directory lxc-start: failed to setup the cgroups for 'generic' lxc-start: failed to setup the container lxc-start: invalid sequence number 1. expected 2 lxc-start: failed to spawn 'generic' You can find the full log file enclosed with the container configuration file. LXC seems to pick the first cgroup subsystem it can get but as that subsystem does not allow the full cgroup operations, LXC fails to start the container. I cannot mount a full cgroup file system as one is already mounted: # mount -t cgroup lxc /cgroup mount : lxc is already mounted or /cgroup is busy What can I do in this kind of situation? Can I specify to LXC where it can find all the cgroup subsystems? ___ Jimmy THRASIBULE <thrasibule.ji...@gmail.com>
