With https://wiki.openstack.org/wiki/InstanceResourceQuota, it is possible to define the maximum disk read rate such as nova flavor-key m1.small set quota:disk_read_bytes_sec=10240000 Is there a way to do the same thing for one VM rather than for a flavor ? If a hypervisor is encountering a high I/O load, we would like to be able to throttle back the IOPS from some of the VMs temporarily.
