We performed a comparison between KVM and RHEV based on our users’ reviews in four categories. After reading the collected data, you can find our conclusion below.
Comparison Results: KVM wins out in this comparison. Users find it very fast and super easy to use and manage. It provides excellent security and scales easily. Many users feel RHEV is lacking in some documentation capabilities and security features and that it can be challenging to scale up when needed.
"It offers a high-availability environment."
"The most valuable feature is hypervisor. I can host at the same time different operating systems in Linux Windows."
"If you prefer command-line, there are all kinds of command-line options."
"Scaling the solution is easy. You just have to add more hardware."
"What I like most about KVM is that it's very easy to use. Everything is built-in, even when writing command lines."
"I like that it's easy to manage. It's also more powerful when it comes to security than others. That point of view is the one consideration. The other consideration is that it's cost-effective."
"The product's scalability is good...It's a very stable product."
"It is an open ecosystem, and we see there is a benefit in open-source solutions."
"What they provide is way beyond the essential requirements of customers."
"This solution is very stable. Much more so than similar products."
"It's a scalable solution."
"It is easy to deal with when comes to application migration and its compatibility with the multiple component applications."
"It is a stable solution...It is a scalable solution."
"The solution makes migration easy."
"I can control and manage everything. I know everything that's cooking inside. This is the best part for me."
"The solution is a great all-round product. The virtualization is especially good."
"Lacks high availability across clusters as well as support for Apache CloudStack."
"Business continuity features need to be added."
"We are not getting good support from KVM, and it is not that user-friendly."
"Technical support could be better. In the next release, I would like to see an improved user interface and dashboard. This type of improvement will make it easy or help our engineers understand the solution from a requirement point of view."
"The main drawback in the solution is probably disaster recovery."
"I have previously used VMware and KVM is easier to use. However, they both have their strengths depending on their use cases. They are mostly equal. One of VMware's advantages is it has better support."
"In KVM, snapshots and cloning are areas where there could be a little more sophistication, like VMware."
"The speed is around thirty percent slower than another competitor. This would be something to work on."
"The biggest improvement would be more third-party direct support for things like backups and provisioning through third-party portals."
"We would like the dashboard feature of this solution to be improved, as it is not very detailed at present."
"In comparison to VMware, this solution isn't as stable. We're testing it right now, and we're not trusting the stability of the product."
"RHEV can improve by keeping pace with new features and new enhancements. They should not be halted or delayed innovation because over the past quarter the enhancements have not been as fast as they have been previously."
"The solution could use network virtualization."
"With RHEV, the cyberattacks should be fewer. I want RHEV to be better protected."
"Customers are not aware of this solution, they can improve by providing more awareness and solution availability."
"Configuring the network interfaces is much better in Ubuntu and should be improved."
