Hello,

Thanks for the prompt answer.

Edward,

Full reboot of both engine and host didn't help.
Most likely there's a consistency problem in the oVirt DB.

Arik,

To which DB I should connect and as which user?
E.g. psql -U user db_name

To the 'engine' database.
I usually connect to it by switching to the 'postgres' user as Strahil described.
 

Thanks again,
- Gilboa
