Red Hat Virtualization Manager Setup | ArkIT

Red Hat Virtualization Manager provides a graphical user interface and a REST API to manage the resources in the environment. The Manager is installed on a physical or virtual machine running Red Hat Enterprise Linux.

Before configuring the Red Hat Virtualization Manager, you must manually configure the Manager database on the remote server. You can also use this procedure to manually configure the Data Warehouse database if you do not want the Data Warehouse setup script to configure it automatically.

[root@rhevm ~]# subscription-manager repos \

> --enable=rhel-8-for-x86_64-appstream-rpms \

Install and configure PostgreSQL database

Initialize the database

[root@rhevm ~]# postgresql-setup --initdb
* Initializing database in '/var/lib/pgsql/data'
* Initialized, logs are in /var/lib/pgsql/initdb_postgresql.log

[root@rhevm ~]# systemctl enable postgresql
Created symlink /etc/systemd/system/ → /usr/lib/systemd/system/postgresql.service.

[root@rhevm ~]# systemctl start postgresql
[root@rhevm ~]# su - postgres -c psql
psql (12.9)
Type "help" for help.

postgres=# create role rhevm with login encrypted password 'rhevm';
postgres=# create database rhevm owner rhevm template template0encoding 'UTF8' lc_collate 'en_US.UTF-8' lc_ctype 'en_US.UTF-8';
postgres=# \c rhevm
You are now connected to database "rhevm" as user "postgres".
rhevm=# CREATE EXTENSION "uuid-ossp";
rhevm=# CREATE LANGUAGE plpgsql;
ERROR: language "plpgsql" already exists
rhevm=# \q

Edit the /var/lib/pgsql/data/pg_hba.conf file to enable md5 client authentication, so that the engine can access the database remotely. Add the following line immediately below the line that starts with local at the bottom of the file. Replace X.X.X.X with the IP address of the Manager or Data Warehouse machine, and replace 0-32 or 0-128 with the CIDR mask length

If configure anything wrong in the configuration file you would see below error message

[root@rhevm ~]# systemctl restart postgresql
Job for postgresql.service failed because the control process exited with error code.
See "systemctl status postgresql.service" and "journalctl -xe" for details.

Edit config file

[root@rhevm ~]# vi /var/lib/pgsql/data/pg_hba.conf

host rhevm rhevm md5

Allow TCP/IP connections to the database. Edit the /var/lib/pgsql/data/postgresql.conf file
and add the following line, replace IP address with your server address.



Red Hat Virtualization Manager Setup

Enable port communication with client

# firewall-cmd --zone=public --add-service=postgresql
# firewall-cmd --permanent --zone=public --add-service=postgresql

Restart the DB service

[root@rhevm ~]# systemctl restart postgresql

Install the package and dependencies for the Red Hat Virtualization Manager, and configure it using the engine-setup command. The script asks you a series of questions and, after you provide the required values for all questions, applies that configuration and starts the ovirt-engine service.

* Please note * : Data Warehouse is required for the engine.
If you choose to not configure it on this host, you have to configure
it on a remote host, and then configure the engine on this host so
that it can access the database of the remote Data Warehouse host.
Configure Data Warehouse on this host (Yes, No) [Yes]:
