BetterLinux CPU throtting requires 4-core servers. Certain other BetterLinux features will work with even 1 core (cloakfs, memory limit, process limit, etc). When running cpud on servers with less than 4 cores, this error appears: Error: cpud requires a minimum of 4 cpus in order to run when using start_throttling rules. [FAILED] If you run this command: [root@centos6-tim ~]# service cpud status This message will appear: cpud is not running |
