Hi
Should we add iov support at rbd level ? I think add iov support
will be valuable for cloud vm which use ceph as the backend.

There's already a WIP PR by Jason for this: https://github.com/ceph/ceph/pull/5898
Though it hasn't been worked on for quite some time.

We'll definitely get it into librbd for the Luminous release and
hopefully get a patch submitted to qemu to conditionally use the new
API to eliminate an unnecessary buffer copy.
