<a href="https://gerrit.ovirt.org/#/q/topic:drivemonitor_event+status:open" rel="noreferrer" target="_blank">https://gerrit.ovirt.org/#/q/topic:drivemonitor_event+status:open</a> is<br>
ready for review. It is the first part of the series needed<br>
<br>
to consume the BLOCK_THRESHOLD event available with libvirt >= 3.2.0 and<br>
QEMU >= 2.3.0.<br>
<br>
Once completed, this patchset will allow Vdsm to avoid polling, thus<br>
greatly improving the system performance and<br>
<br>
eventually close <a href="https://bugzilla.redhat.com/show_bug.cgi?id=1181665" rel="noreferrer" target="_blank">https://bugzilla.redhat.com/show_bug.cgi?id=1181665</a><br>
<br>
<br>
Please note that:<br>
<br>
1. CI fails because the workers are not yet updated to CentOS 7.4 (not<br>
yet released AFAIK!) which will provide libvirt >= 3.2.0.<br>
<br>
2. Few more simple patches will be needed to enable/disable monitoring<br>
in specific flows where we cannot use events (e.g. LSM)<br>
<br>
3. I did initial verification successfully, installing fedora 25 on thin<br>
provisioned disk without issue.<br>
