This is another version of the stuff that I've posted here: https://www.redhat.com/archives/libvir-list/2017-February/msg01391.html which was partially based on the very old discussion at https://www.redhat.com/archives/libvir-list/2015-May/msg00580.html
This version fixes some of the review feedback that I've got and also fixes all the issues pointed out in the original cover letter since I managed to implement the node name detection in a way suitable for this.
The event is useful for mgmt apps using thin-provisioned storage so that they don't have to poll for the disk filling all the time.

Ping? This feature is very sought after by oVirt so that they can start developing their code. I't be great if it would make this release. Thanks. Peter
