Red Hat Virtualization (RHV)

Formerly RHEV

Red Hat Virtualization is the best enterprise-level virtualization software for an organization that needs cost-effective and flexible solutions for its environment. We can easily integrate RHEV with other Red Hat software like OpenStack...etc. RHEV is highly customizable software, which helps us to customize our environment. Since RHEV is an open-source tool, we can install it on any hardware. There is no proprietary dependency.

RHV has the following advantages:

• They have relatively cheaper subscriptions compared to others.
• With the future going to Openstack and containerization migrating to KVM-based virtualization will be easier to migrate to future products.
• The easiness to use Ansible to automate activities on Red Hat Virtualization make it easier to consolidate all your automation tasks using one automation solution.

Compared to oVirt, RHEV is more stable but has fewer capabilities. ESX is far more difficult to automate.

RHEV is an excellent product, includes more features, is less expensive, and has rock solid reliability and is backed with the best Red Hat Support in the industry. RHEV uses KVM under the hood which is used by all the big players in the industry (AWS, Rackspace, etc) to lower their overall costs and improve efficiency and profits and that's why RHEV is an excellent solution!

RHEV offers a decent GUI and many management features, such as an API.

We use them both, as one is not better than the other at all facets required. There is still a need to use both products, as we have not fully switched to RHEV due to vSphere still having an edge over them with edits available to the systems while they are operational or they are suspended. Template importation is still better in vSphere.

VMware ESXi is a more mature technology, as it has been around for a longer period of time. However, automating ESXi installations requires hacking OEM media and an intense amount of knowledge of how ESXi operates under the hood. The WebUI and associated functionality for ESXi is more stable than RHEV, however ESXi does not support open-source community projects such as Gluster, Cinder, or Glance natively and relies on HW RAID, NAS, or SAN to achieve high availability. Additionally ESXi licenses tend to be more expensive than using RHEV or it's freely available sibling oVirt.

Pretty much Open Source sums it up.

RHEV is more stable than oVirt but less capability. Much easier to automate than esx
