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 helpful aspect of KVM is the fact that the interface is so minimal. It includes just what you need to set up the VMs and manage them, and it's very simple to do so."
"The GUI interface makes the management of KVM easier than ever before."
"If you prefer command-line, there are all kinds of command-line options."
"Good screen and keyboard sharing feature."
"Very cost-effective."
"The most valuable feature of KVM is its stability."
"This solution is open source and easy to configure."
"KVM has a rich options set which can be directly used or via wrappers, such as libvirt."
"The solution is overall very good with all the facilities. It is user friendly, easy to configure, has documentation, and support is available."
"Stability and speed are the most valuable aspects."
"I can control and manage everything. I know everything that's cooking inside. This is the best part for me."
"The price is the solution's most valuable aspect. It's much cheaper than, for example, VMware."
"What they provide is way beyond the essential requirements of customers."
"It's a scalable solution."
"The solution is stable."
"The most valuable feature of this solution is the support portal."
"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."
"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."
"In KVM, snapshots and cloning are areas where there could be a little more sophistication, like VMware."
"The initial setup of this solution is more difficult than some of the competing products and it could be improved."
"I have encountered difficulties in getting the tool's documentation."
"Technical support is not top-notch."
"I would like to see more focus on microservices and integration with Kubernetes or OpenShift."
"The solution should be more user friendly. We are struggling with the command lines."
"The availability of technical expertise with the solution may be limited in some areas."
"The solution should be made more user-friendly."
"Red Hat by itself is not scalable. But you can have third party add-ons like Ceph to make it massively scalable."
"We hope that Red Hat can produce a paradigm edition. We are looking for paradigm computing and paradigm storage. Its scalability can be improved. It is not easy to scale, and we hope that Red Hat can provide a more scalable system. They should also provide local service and support. Our customers are looking for a good software vendor to provide professional services."
"The solution could use network virtualization."
"We'd like it if it would be possible on Red Hat Virtualization to possibly connect two or three VMs to the same disk."
"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 Administration of the Oracle database and the SAP ERP needs improvement."
