So something must be wrong in my configuration.
I have changed /usr/share/lxc/config/ubuntu.common.conf:
# lxc.mount.entry = proc proc proc nodev,noexec,nosuid 0 0
lxc.mount.auto = proc:rw
And have not found anything else regarding mounting of /proc
But this does not help.
(server is running Ubuntu Trusty)

After reboot I was up to 3.15 as provided by the host. In both cases
/proc as well as all of the contents was owned by root.

Any ideas? can this be done at all on unprivileged containers?
Hi,
which kernel are yo uon?
I've just noticed that on my utopic (3.16 kernel) laptop I have the
same problem. All of /proc is owned by nobody:nogroup. On my 3.13
kernel /proc is owned by root, including /proc/sys/kernel/shmmax.
So this looks like a new kernel bug.
