Comment 2 for bug 1090654

Old patch abandoned - likely permanently, now split into 4 patches:

new patch at : https://review.openstack.org/#/c/22106/

    Part 4 for blueprint quota-instance-resource, by setting cpu_shares,
    cpu_quota,cpu_period through nova flavor-set with admin credentials,
     the cloud admin can implement flexable policy on VM vcpu to physical
    CPU consumption ratio.

    for example:
    nova flavor-key m1.low_cpu set cpu_quota=10000
    nova flavor-key m1.low_cpu set cpu_period=20000
    the instance of m1.low_cpu can only has a max of 50% CPU consumption
    of a physical CPU computing capability.
