Recent Linux kernels have a new concept of 'CGroups' which is a way to group tasks on the system and apply policy to them as a whole. We already use this in the LXC container driver, to control total memory usage of things runing within a container.
This patch series is a proof of concept to make use of CGroups in the QEMU driver. The idea is that we have a 3 level cgroup hierarchy
- Top level; contains the libvirtd daemon itself - 2nd level: one per libvirt driver, but dos not contain any processes. - 3rd level: one per guest VM. Contains the QEMU process
Why the separate group for the driver ? Do you see partitioning of resources by driver as an important requirement ? David
