Hi Richard,

We've added zero and flush functionality to imageio-daemon.

You can download and test the latest build (for el7/fc) from:

http://jenkins.ovirt.org/job/ovirt-imageio_master_build-artifacts-fcraw-x86_64/11/artifact/exported-artifacts/

The latest documentation and examples for Random I/O:

https://github.com/oVirt/ovirt-imageio/tree/master/examples

Notes:
- We plan to introduce the functionality also to the proxy soon.
- We plan to implement trim later during ovirt 4.2 release: https://gerrit.ovirt.org/89470
- Additional pending patches: https://gerrit.ovirt.org/#/q/status:open+project:ovirt-imageio+branch:master+topic:random-io

Thanks!
Nir & Daniel
