<p class="MsoNormal">Dear Roy,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thank you. I noticed after completing the upgrade of the engine, and update of the hypervisors, that one hypervisor could not enter Maintenance state, as it was showing to be still hosting one VM. However, I could not find which one, the
list showing hypervisor VMs was empty.<o:p></o:p></p>
<p class="MsoNormal">I was able to connect the relation between WARN message and “invisible” VM, and its solved now.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I will definitely look more into vdsm, as it is new to me, thank you, this information is valuable.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I think we can close this case.<o:p></o:p></p>
