[ovirt-users] [4.2.2-1.el7.centos] Image locked and unending task

Thu Mar 15 09:51:04 UTC 2018

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:
