In this article we will setup a Red Hat Enterprise Virtualization (RHV) environment. RHV is based on upstream opensource projects KVM and Ovirt. RHV is composed of Red Hat Enterprise Linux (RHEL which includes KVM) and Red Hat Enterprise Virtualization Management (RHV-M), based on Ovirt. As of this article the latest version is RHV 4.1.
RHV has of late become very interesting to customers looking for alternatives to VMware. Below are a few reasons why you should be interested in RHV:
- 100% opensource no proprietary code and no proprietary licencing.
- Best Hypervisor for running Red Hat Enterprise Linux (RHEL).
- Integrated and built with RHEL, uses SELinux to secure Hypervisor.
- RHV leads VMware in SPECvirt performance and price per performance (last results 2013).
- RHV scales vertically and performs extremely well on 4 or even 8 socket servers.
- All features are included in RHV subscription, no licensing for extra capabilities.
- KVM is future proof and is the defacto standard for OpenStack and modern virtualizations platforms.
RHEV has two separate distinct layers, the hypervisor itself and management. The hypervisor layer, RHEV-H is of course built on Red Hat Enterprise Linux (RHEL) and utilizes KVM for the hypervisor technology. RHEV-H can be configured using pre-built RHEV-H image or using standard RHEL. The management layer, Red Hat Enterprise Virtualization Management (RHEV-M) provides management for a multi-hypervisor environment and uses concepts such as datacenters, clusters, networks and storage domains to describe virtualization resources. In this article we will focus on options for configuring RHEV-M. The upstream opensource project behind RHEV-M is oVirt. There are two options as of RHEV 3.5 for configuring RHEV-M, standalone or hosted engine.
Below are other articles you may find of interest relating to RHEV:
Red Hat Enterprise Virtualization (RHEV) has two options for running a hypervisor host: 1) use the RHEV-H host 2) use Red Hat Enterprise Linux 6 or 7. Option 1 is similar to VMware ESXi, RHEV-H is an optimized OS for running Virtual Machines. Option 2 allows you to configure a standard RHEL 6 or 7 host and add it to RHEV as a hypervisor.

Virtual machine disk images are specific to hypervisors and each hypervisor has its own format. Open Virtual Format (OVF) is a packaging standard designed to address portability and deployment of virtual machines across different hypervisors. Continue reading
Red Hat Enterprise Virtualization has two main components: RHEV-H and RHEV-M. In this post we will be focusing on RHEV-M which provides a REST API and various SDKs. By integrating with RHEV-M we can integrate a powerful set of virtualization APIs into any applications, processes or workflows. Continue reading
