1 Overview of HP OneView for Red Hat Enterprise Virtualization (RHEV) By collecting system health and inventory data and monitoring events from a variety of physical sources, HP OneView for RHEV (formerly HP Insight Control for RHEV) provides information you can use to manage your HP ProLiant hosts and to take appropriate actions as determined by your site policies.
2 Installation Prerequisites Prerequisites for installing HP OneView for RHEV The following are prerequisites for installing HP OneView for RHEV: • RHEV-M must be installed and configured. Refer to Red Hat's documentation for installation and configuration of RHEV-M. • The RHEV-M credentials used during configuration of RHEV-M will be needed. • The postgres password used during configuration of RHEV-M may be needed, depending on the authentication method selected for postgres (“pg_hba.conf”).
2. Configure HP OneView for RHEV by running the setup script hpovrhev_setup.py. The setup script is placed in /usr/local/bin and in the path /usr/lib/hpovrhev-x.x.x.x, so it can be run from any directory. You will need the RHEV-M credentials and you may also need the postgres database password you entered when you ran the rhevm-setup script. [root@rhel51 ~]# hpovrhev_setup.py Welcome to HP OneView for RHEV..... Creating database....
3. In order to use the HP OneView for RHEV reporting functionality, the RHEV-M reporting packages must first be installed as follows: • • Install the following RHEV-M reporting packages on the RHEV-M server: ◦ rhevm-reports-ver.rpm ◦ rhevm-dwh-ver.rpm Execute the reporting package setup scripts: NOTE: • NOTE: 8 Installation For RHEVM 3.4, these scripts are not required.
3 Getting started UI elements Installation of HP OneView for RHEV adds a number of new UI elements to the RHEV-M console, as shown in the figure below and described in the following table.
