In review [1] it was figured out that this is a feature request (=>"wishlist"). The effort is driven by the bp [2] (=> "Opinion"). No need for this bug report anymore.

Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1445637 Title: Instance resource quota not observed for non-ephemeral storage Status in OpenStack Compute (nova): Opinion Bug description: I'm using a nova built from stable/kilo and trying to implement instance IO resource quotas for disk as per https://wiki.openstack.org/wiki/InstanceResourceQuota#IO. While this works when building an instance from ephemeral storage, it does not when booting from a bootable cinder volume. I realize I can implement this using cinder quota but I want to apply the same settings in nova regardless of the underlying disk. Steps to produce: nova flavor-create iolimited 1 8192 64 4 nova flavor-key 1 set quota:disk_read_iops_sec=10000 Boot an instance using the above flavor Guest XML is missing <iotune> entries Expected result: <snip> <target dev='vda' bus='virtio'/> <iotune> <read_iops_sec>10000</read_iops_sec> </iotune> </snip> This relates somewhat to https://bugs.launchpad.net/nova/+bug/1405367 but that case is purely hit when booting from RBD-backed ephemeral storage. Essentially, for non-ephemeral disks, a call is made to _get_volume_config() which creates a generic LibvirtConfigGuestDisk object but no further processing is done to add extra-specs (if any). I've essentially copied the disk_qos() method from the associated code review (https://review.openstack.org/#/c/143939/) to implement my own patch (attached).
