Thanks for that quick answer !
   Yes indeed I had some connectivity troubles on this server, a strange 
bonding problem I am investigating on since yesterday. But with just one link, 
it is working ok, I have no similar errors after the ones you saw.   What can I 
do to really remove the task from the list ? Manual database cleanup ?

 Thank you for sending the logs.   According to the logs, it seems that you had 
some connectivity issue while you tried to preview the snapshot. The preview 
operation rolled back but according to you failed to finish.   It seems like 
you still have a connectivity issue with that host 
('pfm-srv-virt-1.pfm-ad.pfm.loc), try to see what happens to it.   Here is the 
relevant part from the log:    2018-03-14 17:00:48,652+01 ERROR

 Thanks for your reply.   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.   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.   But the preview operation never ended. So I 
restarted the engine vm but nothing changed.   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.   I even remove 
the second disk to see if it was better, but nothing.   You will find the 
engine logfile and the "vdsm.log" from the server the task is running on.   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.centos.noarch   Regards

 Hi,   Can you please specify the version of the engine and supply the 
engine.log and the vdsm.log?   Moreover, can you please specify the steps that 
you did that led you to this issue?   Thanks,

 Hi,
   I tried to rollback to a snapshot on a VM, but the preview never ended.   
The task has been running for about 15 hours, with this state :   {
 "916b67fb-8808-43d2-850c-1c12650ccc49": {
 "verb": "createVolume", 
 "code": 0, 
 "state": "finished", 
 "tag": "spm", 
 "result": {
 "uuid": "d37ca118-820f-46a3-b99b-714018ea8b42"
 }, 
 "message": "1 jobs completed successfully", 
 "id": "916b67fb-8808-43d2-850c-1c12650ccc49"
 }
}
   I just canceled it : the task list is now empty on the CLI but no change on 
GUI.   So I restared the engine VM, but no success.   With 
"/usr/share/ovirt-engine/setup/dbutils/unlock_entity.sh" I was able to manually 
unlock the image, but the task is still "finalizing".   Is this a bug ?    
Regards
