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.
"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."
"If you are a Linux desktop user, KVM is the solution to go with if you have to start virtual machines with Linux or other operating systems with almost zero extra configuration needed."
"Our production servers are running in Linux, and this solution supports that environment well."
"One of the best features of KVM is its user-friendly interface."
"It is easy to use, stable, and flexible. It is a pretty mature product, and it is faster than VirtualBox."
"The tool's most valuable feature is backup. The product makes it easy to manage virtual machines. Other tools require third-party applications like VMware and vSphere. However, KVM doesn't require these applications."
"KVM is stable."
"The most valuable feature of KVM is its stability."
"We find the ease of use of this solution to be invaluable. It is user-friendly and integrates well with other software."
"The most valuable feature of this solution is the support portal."
"Red Hat is the most stable system."
"It is a stable solution...It is a scalable solution."
"The solution is stable."
"This solution is very stable. Much more so than similar products."
"One of the most valuable features of this solution is the popularity of the OS."
"The solution is overall very good with all the facilities. It is user friendly, easy to configure, has documentation, and support is available."
"The grid interface of KVM needs improvement. It could be more beautiful, especially when compared to VMware."
"The solution’s user interface could be improved and made more user-friendly."
"We would like to have a software lifecycle solution included in this solution. We can handle the software needed for KVM, but also the software that we provide. A lifecycle component would be very beneficial."
"Support for VF is needed, where you can, for example, export from VMware to KVM."
"Technical support is not top-notch."
"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."
"Business continuity features need to be added."
"We are not getting good support from KVM, and it is not that user-friendly."
"The Administration of the Oracle database and the SAP ERP needs improvement."
"We'd like it if it would be possible on Red Hat Virtualization to possibly connect two or three VMs to the same disk."
"Configuring the network interfaces is much better in Ubuntu and should be improved."
"The availability of technical expertise with the solution may be limited in some areas."
"A few features of the product do not work as well as those in VMware."
"Red Hat by itself is not scalable. But you can have third party add-ons like Ceph to make it massively scalable."
"Customers are not aware of this solution, they can improve by providing more awareness and solution availability."
"We would like the dashboard feature of this solution to be improved, as it is not very detailed at present."
