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 find the density of the product most valuable. It is density that a technologist can just assign page merging. This is what makes KVM one of the important players of the virtualization market."
"This solution is open source and easy to configure."
"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."
"The product's scalability is good...It's a very stable product."
"I like that this is an open-source solution. It is very powerful, and it's easy."
"Very cost-effective."
"Scaling the solution is easy. You just have to add more hardware."
"The GUI interface makes the management of KVM easier than ever before."
"I can control and manage everything. I know everything that's cooking inside. This is the best part for me."
"It is a stable solution...It is a scalable solution."
"The solution is overall very good with all the facilities. It is user friendly, easy to configure, has documentation, and support is available."
"The most valuable feature of this solution is the support portal."
"The solution makes migration easy."
"We find the ease of use of this solution to be invaluable. It is user-friendly and integrates well with other software."
"One of the most valuable features of this solution is the popularity of the OS."
"RHEV’s cost is much less compared to VMware."
"The product must provide better performance monitoring features."
"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."
"Lacks high availability across clusters as well as support for Apache CloudStack."
"Its resource usage can be improved."
"We still occasionally build Interlaced Wireless Protection within our environment. The ecosystem entails areas, where we support agents, and release backup and security solutions. Collaboration with independent software vendors (ITOLs or ITOLED) is necessary to offer these solutions to customers. However, the scope of the ecosystem in KVM is not as extensive as that of VMware's. In contrast, VMware boasts a robust partner network, allowing for comprehensive customer solutions. On the other hand, KVM’s ecosystem is comparatively limited in comparison. I would like to see FT features in KVM."
"The solution’s user interface could be improved and made more user-friendly."
"The networking with wireless devices needs improvement."
"The stability of this solution is less than other products in the same category."
"We would like the dashboard feature of this solution to be improved, as it is not very detailed at present."
"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."
"Configuring the network interfaces is much better in Ubuntu and should be improved."
"It lags behind in that you need to go to something like Fedora to get all the extra bells and whistles."
"The solution should be made more user-friendly."
"While everything needs improvement in some way, I have no specifics."
"Customers are not aware of this solution, they can improve by providing more awareness and solution availability."
"We'd like it if it would be possible on Red Hat Virtualization to possibly connect two or three VMs to the same disk."
