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.
"KVM is stable."
"I like that this is an open-source solution. It is very powerful, and it's easy."
"It offers a high-availability environment."
"I appreciate the network passcode feature in KVM, as it provides a convenient way to manage DNS and cloud hosting."
"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."
"The most valuable feature is hypervisor. I can host at the same time different operating systems in Linux Windows."
"Scaling the solution is easy. You just have to add more hardware."
"Our production servers are running in Linux, and this solution supports that environment well."
"It is a scalable solution."
"We find the ease of use of this solution to be invaluable. It is user-friendly and integrates well with other software."
"It is easy to deal with when comes to application migration and its compatibility with the multiple component applications."
"It's a scalable solution."
"This solution is very stable. Much more so than similar products."
"Red Hat is the most stable system."
"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."
"I can control and manage everything. I know everything that's cooking inside. This is the best part for me."
"Business continuity features need to be added."
"The networking with wireless devices needs improvement."
"Technical support is not top-notch."
"The grid interface of KVM needs improvement. It could be more beautiful, especially when compared to VMware."
"In KVM, snapshots and cloning are areas where there could be a little more sophistication, like VMware."
"Some things are pretty basic, and they could be more robust with more detail."
"The only negative aspect of needing hardware support is a fully functional KVM can be dropped. It would be nice if the support for other platforms, like ARM or Risk, were as good as the x86 one. However, with the democratization of Chromebooks based on these chips and mobile devices, it will not take long for that to happen."
"I would like to see more focus on microservices and integration with Kubernetes or OpenShift."
"Configuring the network interfaces is much better in Ubuntu and should be improved."
"The availability of technical expertise with the solution may be limited in some areas."
"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 Administration of the Oracle database and the SAP ERP needs improvement."
"There is not any proper documentation on the site to reference."
"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."
"This solution could be more secure."
"It lags behind in that you need to go to something like Fedora to get all the extra bells and whistles."
KVM is ranked 4th in Server Virtualization Software with 38 reviews while RHEV is ranked 10th in Server Virtualization Software with 31 reviews. KVM is rated 8.0, while RHEV is rated 7.6. The top reviewer of KVM writes "Delivers good performance because of kernel-based virtualization". On the other hand, the top reviewer of RHEV writes "The solution is scalable and affordable, but it lacks features, and it is not easy to manage". KVM is most compared with Proxmox VE, Oracle VM VirtualBox, Hyper-V, VMware vSphere and Citrix Hypervisor, whereas RHEV is most compared with VMware vSphere, Proxmox VE, Hyper-V, Oracle VM and Nutanix AHV Virtualization.
