[lxc-users] lxc-start fails with "no systemd controller mountpoint found"

[F Dave]

Hello,

I have a host system running Oracle Linux 6.7 and installed lxc 2.0.0 from
source tarball.

I created a node using:

# lxc-create -n node2 -t download

Distribution: Oracle Linux 6, amd64

I cannot start the node:

[root at devhost ~]# lxc-start -n node2 -l debug -F -o /dev/stdout

I have cgroup mounted:

[root at devhost ~]# uname -a
Linux devhost 3.8.13-68.3.4.el6uek.x86_64 #2 SMP Tue Jul 14 15:03:36 PDT

I read that this may be a bug, and has been fixed:
https://bugs.launchpad.net/ubuntu/+source/lxc/+bug/1556447

Could someone please assist?

Thanks
Davis
