<p class="MsoNormal">Hey Guys,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We Deploy a lot of Templates. We got our Training Environment build in Ovirt.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Our Problem – when we Deploy the Same Template. The VM´s getting slower every Time we deply a new VM from that Template.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">And I really don’t know why. RAM locking good – CPU and Network looking good.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">But it take about 15 Minute to create a new Template based VM – normaly it takes about 30 Seconds.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I checked nload and the Interface traffic – but its not really high.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can someone explain why its getting so slow and how to troubleshoot?<span style="font-size:12.0pt;font-family:"Calibri Light",sans-serif;mso-fareast-language:EN-GB"><o:p></o:p></span></p>
