Kubelet stats

[nuriel77]

Using virt7-container-common-candidate ends up having kubelet run via runc.
This results in:

runc[11144]: E0606 09:51:28.986046   11225 summary.go:92] Failed to get system container stats for "/systemd/system.slice": failed to get cgroup stats for "/systemd/system.slice": failed to get container info for "/systemd/system.slice": unknown container "/systemd/system.slice"

It seems to me that kubelet is unable to access the host's /systemd/system.slice where it can read container stats.
Is this a known issue? How is kubelet supposed to read container stats? (Using Docker as container runtime for all k8s containers)
