Control Groups
Since kernel 2.6.24, Linux has so called control groups as a means to partition available resources between running processes. Libcgroups makes that functionality available to programmers and contains two tools, cgexec and cgclassify, to start processes in a control group or move existing processes from one control group to another.
Our goals are to improve the existing tools where necessary and feasible and/or to create new ones e.g. to create or modify persistent cgroups configuration. At the beginning the focus will be on command line tools, but we'll keep in mind that in the long term we'll likely want to have graphical tools. These would offer similar functionality and we should try to make sure that any non-UI code written is usable from both kinds of frontends.
the procedure how to start cgconfig service:
- create /etc/cgconfig.conf
configuration file (the example is in /samples section)
- for each mount point create the relevant directory and mount it (type of mount is cgroup)
(see howto.txt)
- then you can start the service (stop of this service umount the directory and remove it)
