[ovirt-users] Delete snapshot with status illegal - live merge not possible

[Jan Siml]

Further investigations showed, that the time on the target storage went 
backwards due to a misconfigured NTP service. Someone has corrected the 
configuration while live storage migration was running and the time 
jumped backwards.

Might this be a cause for the issue?
