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 most valuable feature of KVM is its stability."
"The key aspect is that the KVM directly interacts with the Kronos. There's no clear indication of indirect communication with Kronos. It is not linked to Kronos, and interaction is straightforward without any intermediaries."
"Documentation and problem-solving troubleshooting are the most valuable features. Performance (when fine-tuned and with "special" HW) is awesome, equal to or more than other enterprise closed-source solutions."
"I find the density of the product most valuable. It is density that a technologist can just assign page merging. This is what makes KVM one of the important players of the virtualization market."
"It offers a high-availability environment."
"The KVM service is well managed with a central policy interface."
"Good screen and keyboard sharing feature."
"It is an easily scalable solution."
"RHEV’s cost is much less compared to VMware."
"The solution has a good licensing module."
"The solution is overall very good with all the facilities. It is user friendly, easy to configure, has documentation, and support is available."
"The most valuable feature of Red Hat Enterprise Virtualization is its pricing."
"It's a scalable solution."
"We find the ease of use of this solution to be invaluable. It is user-friendly and integrates well with other software."
"Red Hat is the most stable system."
"The most valuable feature of this solution is the support portal."
"Support for VF is needed, where you can, for example, export from VMware to KVM."
"There are some issues with the graphics and some software that is very complex."
"I have encountered difficulties in getting the tool's documentation."
"Some things are pretty basic, and they could be more robust with more detail."
"Its resource usage can be improved."
"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 grid interface of KVM needs improvement. It could be more beautiful, especially when compared to VMware."
"The KVM tech support is really bad. They are not very responsive."
"The documentation is not as good as it should be."
"The solution has a very small lifecycle."
"Customers are not aware of this solution, they can improve by providing more awareness and solution availability."
"While everything needs improvement in some way, I have no specifics."
"This solution could be more secure."
"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."
"Red Hat by itself is not scalable. But you can have third party add-ons like Ceph to make it massively scalable."
"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."
