Hello Willfu,

We are working on a feature to add to flavor types that allows the
administrator to specify the disk i/o operations. You get to specify the
weight for the blkiotune parameter (from 100 to 1000) for the flavor that
you created. This information would get stored as part of the instance type
extra specs table. In the first step of our feature development, you get to
create a instance type with this parameter. In the second part of our
developoment we will allow VM creation based on the flavor type and take
into consideration the blkiotune weight that is associated with the flavor
type.

We have not created a blueprint at this stage. Maybe we should. This is a
group effort as part of the openstack hackathon that meets regularly at
Yahoo in SF south bay.
