To manage the redhat enterprise virtualization hypervisor (RHEV-H) , you have to configure the Redhat Enterprise Virtualization Manager (RHEV-M) on Redhat Enterprise Linux 6.x operating system. RHEV-M provides a feature rich graphical based web interface to manage the virtual infrastructure from single point. It provides host management ,guest management,storage management and high availability infrastructure. We can access the web-portal on both “http” and “https” with ports 90 and 443 respectively.By default RHEV-M uses “postgresql” database but we can also provide the external database to setup the RHEV-M environment. Let’s see how we can install and configure the Redhat Enterprise virtualization Manager.
Prerequisite:
- Redhat Enterprise Linux 6.x Operating System with internet connectivity
- Redhat Valid Subscription account or Trail account.
Registering RHEL 6.x with Redhat Network.
1. Login to Redhat Linux 6.x host and register with Redhat network using the valid Redhat Enterprise virtualization Subscription.
- Gnome-> System – > Register with RHN network or
- command line – Execute “rhn_register”.
2.Go with “Redhat Classic network”. If your system requires proxy for internet connection, click on “Advance network configuration” to enter the proxy information.
3.Enter the username /password to connect to redhat network.
4.Select the system update model. If you do not want to update the system with major release, just select “Limited Updates” .
I am proceeding with “All Available Updates” since its a LAB environment.Click Yes to continue
.5.Create the system profile.
6.Review the subscription details and click forward to continue.
7.Click to finish the registration.
8.Open a terminal or login to server using ssh. Add the redhat channel for the software update.
# rhn-channel --add --channel=rhel-x86_64-server-6 # rhn-channel --add --channel=rhel-x86_64-server-supplementary-6 # rhn-channel --add --channel=rhel-x86_64-server-6-rhevm-3.4 # rhn-channel --add --channel=jbappplatform-6-x86_64-server-6-rpm
9.Install the RHEV-M rpm using below command.
[root@UARHEVM ~]# yum install rhevm Loaded plugins: product-id, rhnplugin, security, subscription-manager, versionlock Updating certificate-based repositories. Unable to read consumer identity Setting up Upgrade Process Resolving Dependencies --> Running transaction check ---> Package rhevm.noarch 0:3.1.0-55.el6ev will be updated --> Processing Dependency: rhevm = 3.1.0-55.el6ev for package: rhevm-notification-service-3.1.0-55.el6ev.noarch --> Processing Dependency: rhevm = 3.1.0-55.el6ev for package: rhevm-dbscripts-3.1.0-55.el6ev.noarch --> Processing Dependency: rhevm = 3.1.0-55.el6ev for package: rhevm-userportal-3.1.0-55.el6ev.noarch --> Processing Dependency: rhevm = 3.1.0-55.el6ev for package: rhevm-restapi-3.1.0-55.el6ev.noarch --> Processing Dependency: rhevm = 3.1.0-55.el6ev for package: rhevm-backend-3.1.0-55.el6ev.noarch --> Processing Dependency: rhevm = 3.1.0-55.el6ev for package: rhevm-genericapi-3.1.0-55.el6ev.noarch --> Processing Dependency: rhevm = 3.1.0-55.el6ev for package: rhevm-tools-common-3.1.0-55.el6ev.noarch --> Processing Dependency: rhevm = 3.1.0-55.el6ev for package: rhevm-webadmin-portal-3.1.0-55.el6ev.noarch
10.Once the RHEV-M is installed, just begin the RHEV-M configuration using “engine-setup” command.According to my environment , i have answered to “engine-setup” questions. Please alter it according to your environment.

12. You can access the Redhat Enterprise Virtualization Manager from the web using below mentioned web links.
- http://Server-IP:80/ovirt-engine
- https://Server-IP:443/ovirt-engine
We have successfully installed and configured the Redhat Enterprise virtualization Manager . In the next article, we will see how to play with RHEV-M web portal and creating the virtual Machines. Stay Tuned with UnixArena.

Hi, I’ve added an additional 32GB RAM on my server but it is not reflecting in my Hypervisor. Any hint is good. Thanks.
New to Redhat.
