Hello, I'm trying to install oVirt 3.1, using an external postgres db running on RHEL6 (postgresql-server-8.4.12-1.el6_2.x86_64). I'm getting the following error during engine-setup: Error: uuid-ossp extension is not loaded into the DB. Verify with the DB admin that uuid-ossp extension is loaded into newly created databases and rerun the setup. The database log indicates: ERROR: function uuid_generate_v1() does not exist at character 8 HINT: No function matches the given name and argument types. You might need to add explicit type casts. STATEMENT: SELECT uuid_generate_v1(); I did some searching, and it appeared that I might need to add some postgres-contrib functions: psql -U postgres -d engine -f /usr/share/pgsql/contrib/uuid-ossp.sql Unfortunately, it appears that the install script wants to create a temporary database and expects these functions to exist on its newly-created temp DB, not an already-existing database. Has anyone else been bitten by this? Or have any ideas how to address this? Thanks, Ian
