</p><blockquote>
<pre>Specifically for IO statistics, VDSM reads the values from libvirt[1].
cgroup limiting is possible if you define it, but is unrelated.
Also note that 7.3 is a bit ancient, I'm not sure how supported it is with
latest 4.1 - which I'm sure will pull new dependencies from 7.4 (for
example, libvirt!).</pre>
</blockquote>
We use oVirt 4.1.6 on 7.4 of course.<p></p>
<p>Where I can see IO stat? I never see this on oVirt manager.</p>

cgroup blk metric collection?</span><br>
<span>Perhaps this is an outdated way and metrics
should be collected in a different way and it should be
