Hello,
if no one has an idea how to correct the Disk/Snapshot paths in Engine
database, I see only one possible way to solve the issue:
Stop the VM and copy image/meta files target storage to source storage
(the one where Engine thinks the files are located). Start the VM.
Any concerns regarding this procedure? But I still hope that someone
from oVirt team can give an advice how to correct the database entries.
If necessary I would open a bug in Bugzilla.
Kind regards
