Recent Linux kernels have a new concept of 'CGroups' which is

group tasks on the system and apply policy to them as a whole. We already

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 ?
