To Install RHEV 3.5 in Linux

RHEV stands for Red Hat Enterprise Virtualization, which is a desktop and server platform from the Red Hat based on KVM hypervisor. It provides a RHEL-based centralized management server with a web-based interface to manage the virtual machines (VMs). In this article, we will learn the various steps to install RedHat Enterprise Virtualization (RHEV).

Features

  • OpenStack integration.
  • Supported Daily missions like offline migration, High availability, Clustering, etc.
  • Open source solution based on the Red Hat Enterprise Linux kernel with the Kernel-based Virtual Machine (KVM) hypervisor technology.
  • Supports limit upto 160 logical CPUs and 4TB per host and up to 160 vCPU and 4TB vRAM per virtual machine.

To Install RedHat Enterprise Virtualization Manager

Get a free 60 day trail subscription from the redhat official site using the coporate mail account. Register the system using the subscription_manager command

[root@linuxhelp2 ~]# subscription_manager register --username username --password password
The system has been registered with id: 030c633d-6dec-4284-86ee-3abaa92deb71

To subscribe, use the rhn_register command

[root@linuxhelp2 ~]# rhn_register


Update the system by using the following command.

[root@linuxhelp2 ~]# yum update

Loaded plugins: product-id, rhnplugin, search-disabled-repos, subscription-
