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.
"The performance is great."
"I have found KVM to be scalable."
"The product's scalability is good...It's a very stable product."
"It offers a high-availability environment."
"A very reliable solution which can be used for x86 architecture virtualization with reasonable overhead."
"Good screen and keyboard sharing feature."
"The most valuable feature is hypervisor. I can host at the same time different operating systems in Linux Windows."
"This solution is open source and easy to configure."
"The solution is stable."
"Stability and speed are the most valuable aspects."
"Customers are moving to open source and Red Hat is the leader in this particular space. I think customers feel more confident running Red Hat Virtualization than VMware."
"We find the ease of use of this solution to be invaluable. It is user-friendly and integrates well with other software."
"This solution is very stable. Much more so than similar products."
"The solution is a great all-round product. The virtualization is especially good."
"It is easy to deal with when comes to application migration and its compatibility with the multiple component applications."
"The most valuable features of RHEV are all the tools, such as virtualization, management of cloud platforms, and integration of container environments. The solution has good compatibility between virtualization, content management, and cloud management. Having the full set of these tools is the advantage of it."
"The solution’s user interface could be improved and made more user-friendly."
"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."
"The only negative aspect of needing hardware support is a fully functional KVM can be dropped. It would be nice if the support for other platforms, like ARM or Risk, were as good as the x86 one. However, with the democratization of Chromebooks based on these chips and mobile devices, it will not take long for that to happen."
"I have encountered difficulties in getting the tool's documentation."
"The grid interface of KVM needs improvement. It could be more beautiful, especially when compared to VMware."
"We are not getting good support from KVM, and it is not that user-friendly."
"Some things are pretty basic, and they could be more robust with more detail."
"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 biggest improvement would be more third-party direct support for things like backups and provisioning through third-party portals."
"With RHEV, the cyberattacks should be fewer. I want RHEV to be better protected."
"While everything needs improvement in some way, I have no specifics."
"The UI should be more interactive with additional features."
"The documentation is not as good as it should be."
"The availability of technical expertise with the solution may be limited in some areas."
"Customers are not aware of this solution, they can improve by providing more awareness and solution availability."
"The solution should be made more user-friendly."
