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 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."
"It is easy to use, stable, and flexible. It is a pretty mature product, and it is faster than VirtualBox."
"The KVM service is well managed with a central policy interface."
"I appreciate the network passcode feature in KVM, as it provides a convenient way to manage DNS and cloud hosting."
"The performance is great."
"The initial setup was very easy."
"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."
"What I like most about KVM is that it's very easy to use. Everything is built-in, even when writing command lines."
"One of the most valuable features of this solution is the popularity of the OS."
"The most valuable feature of Red Hat Enterprise Virtualization is its pricing."
"The most valuable feature of this solution is the support portal."
"The solution makes migration easy."
"Customers are moving to open source and Red Hat is the leader in this particular space. I think customers feel more confident running Red Hat Virtualization than VMware."
"It is easy to deal with when comes to application migration and its compatibility with the multiple component applications."
"What they provide is way beyond the essential requirements of customers."
"Red Hat is the most stable system."
"Lacks high availability across clusters as well as support for Apache CloudStack."
"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."
"Some things are pretty basic, and they could be more robust with more detail."
"Monitoring and resolution could be improved."
"Support for VF is needed, where you can, for example, export from VMware to KVM."
"The stability of this solution is less than other products in the same category."
"I would like to see more focus on microservices and integration with Kubernetes or OpenShift."
"There are some issues with the graphics and some software that is very complex."
"The solution could use network virtualization."
"The documentation is not as good as it should be."
"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."
"It lags behind in that you need to go to something like Fedora to get all the extra bells and whistles."
"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 solution should be made more user-friendly."
"The Administration of the Oracle database and the SAP ERP needs improvement."
"While everything needs improvement in some way, I have no specifics."
