<div>Yesterday, I realized I was doing nothing good with some the software I planed to install in a VM, so I tried to revert to a snapshot a took just after OS installation, as I always do.</div>
<div> </div>
<div>As I had added a second disk to the VM in between, I choose to revert to snapshot without taking care of the second disk contents.</div>
<div> </div>
<div>But the preview operation never ended. So I restarted the engine vm but nothing changed.</div>
<div> </div>
<div>This morning I tried to cleanup things, using "taskcleaner" and "unlock_entity". I could regain control over the VM, but the task is still in "finalizing" state in the GUI.</div>
<div> </div>
<div>I even remove the second disk to see if it was better, but nothing.</div>
<div> </div>
<div>You will find the engine logfile and the "vdsm.log" from the server the task is running on.</div>
<div> </div>
<div>I am not sure how to check engine version precisely, so I queried the rpm database in the vm : ovirt-engine-4.2.2-1.el7.<wbr>centos.noarch</div>
<div> </div>
<div>Regards</div>
