Both libvirt and systemd make use of cgroups and resource tunables to be set and the libcgroup project provides some command line tools for managing croups. Despite this, however, it is difficult/impossible for an admin to use these to do effective system partitioning. The guidelines on how applications should co-operate in use of the cgroups hiearchy are flawed, leading applications to setup a hiearchy that cannot be used to do system partitioning. Another part of the problem is that there is no single high level view for the admin across all the "objects" using cgroups - the cgroups tools themselves are too low level, focusing on controllers & processes, rather than concepts like "resource groups", 'system service', 'virtual machine', etc. This feature will seek to address the manageability problems with cgroups to facilitate system partitioning / workload isolation. The guidelines on using the cgroup hiearchy will be updated to allow a more practical hiearchy to be created by applications like systemd/libvirt out of the box. A library and corresponding command line tool will be written to provide a high level view of objects needing resource management. This will allow an administrator to easily define resource groups with different performance characteristics and control placement of system services and virtual machines into those groups. Follow on work will also look at how to extend the controls to user sessions, and ad-hoc commands which may be invoked by users, as well as other non-cgroup based resource tunables under sysfs / procfs. _______________________________________________ devel-announce mailing list devel-announce@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel-announce -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
