Description

In RHEL7, the CPU controller is named "cpu,cpuacct". The comma in the controller name leads to container launch failure.

RHEL7 deprecates libcgroup and recommends the user of systemd. However, systemd has certain shortcomings as identified in this JIRA (see comments).

This JIRA only fixes the failure, and doesn't try to use systemd.
