We have the same problem in lxcSetVcpuBWLive.
cleanup:
    if (period) {
        rc = virCgroupSetCpuCfsPeriod(cgroup, old_period);
        if (rc < 0)
            virReportSystemError(-rc,
                                 _("%s"),
                                 "Unable to rollback cpu bandwidth period");
    }

it seems copied from qemuSetupCgroupVcpuBW.
