Hi,
Ovirt 4.3.9.4-1.el7, CentOS7...
colleague of me tried yesterday do a snapshot preview on his vm but
operation got stalled.
I can see in Task list in Manager operation "Preview VM Snapshot před AD
test of VM install_W10_LTSC-REK" in state Finalizing (6 hours ago)
In the Events I see
May 19, 2020, 4:00:17 PM
Failed to complete Snapshot-Preview před AD test for VM
install_W10_LTSC-REK.

greping correlation id on failed snapshot preview shows only INFO

I am about to try unlock that snapshot but for sure...
* how can I be sure that snapshot operations is not still running (it
would be nice to have some sort of progress bar o better reporting what
is happening in Manager...)
* looks it like bug? Should I fill bugreport or publish more logs?
Cheers,
Jiri
