Public bug reported:
I have a host where I create a privileged Xenial container. Inside that
privileged container, I create an unprivileged Xenial container using
the ubuntu user in the privileged container. When I try starting the
unprivileged container, I get the following error:
lxc-start 20160209133200.970 INFO lxc_cgroup -
cgroup.c:cgroup_init:65 - cgroup driver cgroupfs initing for test-lxc
lxc-start 20160209133200.971 ERROR lxc_cgfs - cgfs.c:cgfs_init:2248 -
cgroupfs failed to detect cgroup metadata
lxc-start 20160209133200.971 ERROR lxc_start - start.c:lxc_spawn:1023
- failed initializing cgroup support
lxc-start 20160209133200.971 ERROR lxc_start -
start.c:__lxc_start:1273 - failed to spawn 'test-lxc'
've tried both Trusty host w/ ppa:ubuntu-lxc/lxc-stable installed and a
Xenial host with the same results. I've also tried using ppa:ubuntu-
lxc/daily in the privileged Xenial LXC.
