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.
"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."
"It offers a high-availability environment."
"There is a strong emphasis on availability, and they have numerous API interfaces for distributed storage and the solution is quite known for its openness."
"The performance is great."
"The initial setup was simple."
"Good screen and keyboard sharing feature."
"The initial setup was very easy."
"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 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."
"There aren't any bugs on the solution."
"Technically, the main reason why I'm using Red Hat is because of its stability."
"This solution is very stable. Much more so than similar products."
"Red Hat is the most stable system."
"The solution is stable."
"I can control and manage everything. I know everything that's cooking inside. This is the best part for me."
"Support for VF is needed, where you can, for example, export from VMware to KVM."
"Technical support is not top-notch."
"Its resource usage can be improved."
"One problem I have is that it's not very scalable when it comes to resizing the VM disk dimensions. For example, if you have initially set a virtual drive to 10 GB and you want to upgrade it to 15 GB, it's not that easy."
"I believe KVM offers a unified answer, while ProxMark addresses orchestration. KVM lacks orchestration. If the aim is to centrally oversee multiple KVMs – let's say to freeze them – a centralized management solution is absent."
"The solution should be more user friendly. We are struggling with the command lines."
"Monitoring and resolution could be improved."
"Business continuity features need to be added."
"The biggest improvement would be more third-party direct support for things like backups and provisioning through third-party portals."
"It lags behind in that you need to go to something like Fedora to get all the extra bells and whistles."
"The availability of technical expertise with the solution may be limited in some areas."
"The UI should be more interactive with additional features."
"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."
"Customers are not aware of this solution, they can improve by providing more awareness and solution availability."
"The solution could use network virtualization."
"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."
