And now after restarting the ovirt-engine.service, first open the web portal pages is instantaneous!<br>
It works.<br>
Thank you.<br>

But now the question arises, in what cases can be a helpful ovirt-warmup.service (<a href="https://github.com/geertj/ravstack/blob/master/share/ovirt-warmup.service" rel="noreferrer" target="_blank">https://github.com/geertj/<wbr>ravstack/blob/master/share/<wbr>ovirt-warmup.service</a>) ?<br></blockquote><div><br></div><div>No idea, I guess ravstack developer wanted to ensure ovirt-engine was responding before continuing the boot sequence.</div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
