> 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.
