And now after restarting the ovirt-engine.service, first open the web portal pages is instantaneous!<br>
It works.<br>
Thank you.<br></blockquote><div><br></div>Yes, the issue was the lack of entropy.<br>haveged on a VM works but the quality of its entropy is still debated.<br>A better solution is to use the paravirtualized VirtIO RNG device.</div><div class="gmail_quote"><br></div><div class="gmail_quote">We already have it on the first boot; we are working to ensure it's always there also after the engine imported the engine VM:<br><div><a href="https://gerrit.ovirt.org/#/c/62334/">https://gerrit.ovirt.org/#/c/62334/</a><br></div><div> </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

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>

<div class="gmail-HOEnZb"><div class="gmail-h5">> This looks like not enough entropy on the host / guest running ovirt-engine.<br>
> If you're on Hosted Engine I suggest to install haveged (in EPEL repo) and run it to ensure enough entropy is available for the VM.<br>
