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 product is really good...One can get good performance because of kernel-based virtualization."
"I like that this is an open-source solution. It is very powerful, and it's easy."
"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."
"Our production servers are running in Linux, and this solution supports that environment well."
"The GUI interface makes the management of KVM easier than ever before."
"It is an easily scalable solution."
"The most valuable feature is hypervisor. I can host at the same time different operating systems in Linux Windows."
"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."
"It is very stable."
"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 has a good licensing module."
"We find the ease of use of this solution to be invaluable. It is user-friendly and integrates well with other software."
"Technically, the main reason why I'm using Red Hat is because of its stability."
"The most valuable feature of this solution is the support portal."
"RHEV’s cost is much less compared to VMware."
"One of the most valuable features of this solution is the popularity of the OS."
"Monitoring and resolution could be improved."
"The main drawback in the solution is probably disaster recovery."
"Lacks high availability across clusters as well as support for Apache CloudStack."
"We are not getting good support from KVM, and it is not that 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."
"Technical support is not top-notch."
"The solution should be more user friendly. We are struggling with the command lines."
"I have encountered difficulties in getting the tool's documentation."
"With RHEV, the cyberattacks should be fewer. I want RHEV to be better protected."
"Configuring the network interfaces is much better in Ubuntu and should be improved."
"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."
"We'd like it if it would be possible on Red Hat Virtualization to possibly connect two or three VMs to the same disk."
"The documentation is not as good as it should be."
"The UI should be more interactive with additional features."
"The solution has a very small lifecycle."
"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."
