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.
"Our production servers are running in Linux, and this solution supports that environment well."
"The KVM service is well managed with a central policy interface."
"Good screen and keyboard sharing feature."
"The most valuable feature of KVM is its stability."
"If you prefer command-line, there are all kinds of command-line options."
"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."
"I have found KVM to be scalable."
"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."
"The initial setup is fairly straightforward and well-documented. The process is very similar to its competitors. The success of your setup depends on how well you plan."
"It is very stable."
"It is easy to deal with when comes to application migration and its compatibility with the multiple component applications."
"The solution has a good licensing module."
"RHEV’s cost is much less compared to VMware."
"Stability and speed are the most valuable aspects."
"The most valuable feature of Red Hat Enterprise Virtualization is its pricing."
"It's a scalable solution."
"The speed is around thirty percent slower than another competitor. This would be something to work on."
"Support for VF is needed, where you can, for example, export from VMware to KVM."
"One thing that maybe could be improved is making it easier to scale. It needs to be more clear on how to scale the storage space for virtual machines."
"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."
"KVM is very difficult to manage and run on daily operations."
"I would like to see more focus on microservices and integration with Kubernetes or OpenShift."
"Monitoring and resolution could be improved."
"The Administration of the Oracle database and the SAP ERP needs improvement."
"When we do a direct comparison, then obviously VMware does better in terms of having Fault Tolerance and doing active disaster recovery and these kind of things. This is something that can be improved within Red Hat."
"It would be better to have more patches, especially kernel-level updates, live and online so that we can keep the business up and running during this period."
"The solution could use network virtualization."
"We would like the dashboard feature of this solution to be improved, as it is not very detailed at present."
"This solution could be more secure."
"The solution has a very small lifecycle."
"With RHEV, the cyberattacks should be fewer. I want RHEV to be better protected."
