Hi,

i am trying to set io limits for VM with:
nova flavor-key lb_proxy set quota:disk_total_bytes_sec=1024
nova flavor-key lb_proxy set quota:disk_total_iops_sec=20

but when i check virsh dumpxml instance-id, it shows it is only set for
device='cdrom' (thats --config-drive), but no <iotune>...</iotune> is
set for cinder volume <disk device='disk'>..</disk>.
I am missing something or cinder volumes has no support for io limits ?

(testing) root at test-osmng:~# nova flavor-show lb_proxy |grep
extra_specs 
| extra_specs | {"quota:disk_total_iops_sec": "20",
"quota:disk_total_bytes_sec": "1024"} |
