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.

Config Nova to use these feathers
1; set IO limit for the specified instance type
nova-manage flavor set_key --name m1.small --key read_bytes_sec --value 10240000 nova-manage flavor set_key --name m1.small --key write_bytes_sec --value 10240000
2;set CPU limit for the specified instance type
nova-manage flavor set_key --name m1.small --key cpu_quota --value 5000 nova-manage flavor set_key --name m1.small --key cpu_period --value 2500
3;set Bandwidth limit for instance network traffic
nova-manage flavor set_key --name m1.small --key inboud_average --value 10240 nova-manage flavor set_key --name m1.small --key outboud_average --value 10240
for the details about bandwidth inbound_peak,inbound_burst,outbound_peak,outbound_burst refer to
