Hi there, Redhat is going to include cgroups in the new RHEL-6, which is a great way to do quality of service (QoS) control on the resources, such as VM CPU, memory, network etc. Especially on CPU power, I remember the OpenNebula template has a variable CPU but it is not really used under KVM but rather a scheduling criteria. With cgroups, the CPU can have a meaning used to give each VM their proper share of the system computing power. I wonder if there is any plans to integrate this into OpenNebula.
Thank you very much. -- Shi Jin, Ph.D.
