We are using RHEV for the virtualization of servers in our environment. Currently, we are using RHEV for nonproduction servers. The best part of RHEV is an open source product in virtualization technology, it is vendor-independent software and a lot more cost-effective and flexible than proprietary solutions. We are managing 100 plus Virtual machines with RHEV in our environment and using the hardware efficiently as well as saving the cost of our project.
Pros
RHEV allow us to install the Operating system image on virtual machines very quickly.
RHEV is an open-source tool, we can easily integrate the solution on any hardware and do a lot of customization.
RHEV is manageable through a Graphical User Interface, which makes it easy for the end-user to manage the RHEV.
Works well on Patching tasks.
Cons
Documentation of RHEV needs more improvement.
RHEV GUI needs a lot of improvements in some versions of RHEV, GUI will not work properly (shows incorrect details of VM ).
Need fast rollout of patch releases.
Need good linux Knowledge to manage the RHEVM.
Likelihood to Recommend
RHEV is well suited for organizations that need a cost-effective and flexible solution for their environment. As its vendor-independent software, easily install on any type of hardware. RHEV provides a GUI interface to manage the software, which makes the management of the software easier for the end-user. RHEV is best for non-production or less critical applications. RHEV can be easily integrated with other REDHAT software.
Red Hat Virtualization is used to host virtual machines for our telecommunications applications.
Pros
1- It easy to upload qcow2 images from the browser.
2- It is easy to automate repetitive tasks with Ansible using RHVM API.
3- It is easy to patch the hypervisors.
Cons
1- RHVM API is pretty slow, especially after creating a VM it is not possible to retrieve the VM details (i.e VM's MAC Address) fast enough, where we need to place a pause in our Ansible Playbook, make the automation process slow.
2- RHV is still using collected to monitor the hypervisors which is deviating from Red Hat policy for other RHEL based applications to use PCP to monitor, which is richer in features.
3- It will be great if it is possible to patch the hypervisors using other tools such as satellite and not only via RHVM.
4- In the past Red Hat used to present patches in the z release (i.e. 4.3.z), and features in the y release (i.e 4. y), but starting from 4.4 that is mixed together wherein the Z release you get both patches and features, that is not good because that requires a lot of time to test when we patch as it includes features as well.
5- Engineering team has to be more reactive when new feature is requested.

Red Hat Virtualization is suitable for small implementation and hosting VMs. However, when you start asking for additional features or enhancements, the engineering team is not the flexible as other engineering teams in Red Hat. It is very likely they will not accept adding features or in the best case. They wouldn't commit to a plan when it is possible to be available.
Due to its inclusion in RedHat, RHV is utilized as a one-stop solution for virtual environments. The installation expenses of such a system pose a significant challenge for businesses. We're utilizing RHV instead of VSphere since it's more cost-effective and easier to integrate with KVM.
Pros
RHV issues/bugs can be reported via Bugzilla to RH support. The service is great and typically responds soon.
Red Hat distribution integration is seamless as it is integrated into the kernel.
OpenStack support enables more customized VM templates and network configuration control.
Cons
If the aforementioned can't be done, additional open-source tool compatibility or support.
Likelihood to Recommend
When it comes to managing virtual machines, RHV is the best choice. RHV is a good option if you deal with OpenStack, as it has built-in support for it. In this case, you may not be able to justify the expense. However, adopting something like oVirt (which is related to but not identical to RHV) might be preferable despite the fact that oVirt is not built into the kernel.

We have many servers in our organization running Linux. We have hosted many virtual machines on the same, and many of the company applications are running on those VMs resulting in a cost-effective solution as well as time-saving as it reduces the need for hardware every time our company has IT needs.
Pros
Creating multiple VMs
Save costs as it is open source and comes as Linux kernel Module
Reduces need of multiple hardware everytime you need to scale up
Cons
Sometimes it can be complicated to handle
You need support tools for setting up, without it can be complex
Sometimes performance can drop down
Likelihood to Recommend
If any organization wants to run many many apps with minimal hardware and minimum costing, then it is the best solution. There is no extra cost involved, it comes free with Linux and is open source. If given proper training one or two times, it is easy to install and use as well.
We use RHEV across the organization from RND all the way down to our customer support operations. Every level has their own requirements and expectations from software and its use, RHEV provides the organization with a scalable virtualization platform that answers more of todays needs than competitors. We host systems for companies wanting a cloud based solution and the performance from RHEV is right on par with what our needs are.
Pros
RHEV can acquire user and group information from an Active Directory service without a great deal of confusing configuration.
RHEV management is browser-based and can be accessed from any platform.
Online Snapshot capability, provides a better redundancy than vsphere.
Cons
Hot Swappable functionality could be improved upon.
Template importation from external sources.
Better database synchronization when implemented.

Red Hat Enterprise Virtualization has provided the flexibility we need to offer a highly reliable and scalable cloud solution to our customers. As one of the leading security providers in the world, Red Hat Enterprise Virtualization will deliver unparalleled experience to our customers as we embark on a new shift in operations. Our organization has just shifted focus to provide a more robust offering and we were not able to do so without RHEV. There are still some instances where vmware has redhat beat purely due to their maturity in the space.
