The base environment used here is CentOS 7.
- Install ovirt-engine:
yum install -y http://resources.ovirt.org/pub/yum-repo/ovirt-release41.rpm yum install ovirt-engine -y
- Start postgres container:
docker run --name=postgresql -d -p 5432:5432 registry.centos.org/centos/postgres:latest
- Prepare the PostgreSQL database according to the guide below: https://www.ovirt.org/documentation/install-guide/appe-Preparing_a_Remote_PostgreSQL_Database_for_Use_with_the_oVirt_Engine/
docker exec -ti postgresql bash su - postgres psql postgres=# create role engine with login encrypted password 'password'; postgres=# create database engine owner engine template template0 encoding 'UTF8' lc_collate 'en_US.UTF-8' lc_ctype 'en_US.UTF-8'; postgres=# \q vi /var/lib/pgsql/data/pg_hba.conf
Ensure the database can be accessed remotely by enabling md5 client authentication. Edit the /var/lib/pgsql/data/pg_hba.conf file, and add the following line immediately underneath the line starting with local at the bottom of the file, replacing X.X.X.X with the IP address of the Engine:
host database_name user_name X.X.X.X/32 md5
postgresql.conf and add following lines:
vi /var/lib/pgsql/data/postgresql.conf autovacuum_vacuum_scale_factor = 0.01 autovacuum_analyze_scale_factor = 0.075 autovacuum_max_workers = 6 maintenance_work_mem = 65536 max_connections = 150 lc_messages = 'en_US.UTF-8'
- Restart the database within the container:
-bash-4.2$ pg_ctl restart exit exit
- Setup ovirt-engine:

You should be able to access oVirt’s web portal at the address mentioned above.
Notes: When you first start your machine, be sure to start the Docker container that has your database.
After this, restart the
ovirt-engine service using the following command:
systemctl restart ovirt-engine
Do use the image pulled from registry.centos.org/centos/postgres:latest. The one provided by PostgreSQL is difficult to configure since it seems intended to use as is. Your mileage on this may vary. The 404 error that appears initially should disappear and you should get the web login page for oVirt, after a few seconds or so.
