InstanceResourceQuota
Instance Resource Quota
How to set Server CPU,disk IO,Bandwidth consumption limit for instances using the new feather of nova. By using cgroup,libvirt can set the per instance CPU time consumption percent. and the instances's read_iops,read_byteps, write_iops,write_byteps.also libvirt support limit the instances in/out bandwidth.
