[Bug 936756] Re: lxc complains about cgroup not available

[Serge Hallyn]

@Ritesh,

actually lxc-create doesn't need the cgroups, so that doesn't mean there
is no problem.  However, your mount output only shows that a tmpfs
called cgroup is mounted under /sys/fs/cgroup.  It doesn't show that
actual cgroup filesystems are mounted under there.  Take a look at
/proc/self/mounts, and you should see something like:

serge at ubuntu:~$ grep cgroup /proc/self/mounts
cgroup /sys/fs/cgroup tmpfs rw,relatime,mode=755 0 0
cgroup /sys/fs/cgroup/cpuset cgroup rw,relatime,cpuset 0 0
cgroup /sys/fs/cgroup/cpu cgroup rw,relatime,cpu 0 0
cgroup /sys/fs/cgroup/cpuacct cgroup rw,relatime,cpuacct 0 0
cgroup /sys/fs/cgroup/memory cgroup rw,relatime,memory 0 0
cgroup /sys/fs/cgroup/devices cgroup rw,relatime,devices 0 0
cgroup /sys/fs/cgroup/freezer cgroup rw,relatime,freezer 0 0
cgroup /sys/fs/cgroup/blkio cgroup rw,relatime,blkio 0 0
cgroup /sys/fs/cgroup/perf_event cgroup rw,relatime,perf_event 0 0
