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 has a rich options set which can be directly used or via wrappers, such as libvirt."
"I have found KVM to be scalable."
"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."
"I like that this is an open-source solution. It is very powerful, and it's easy."
"What I like most about KVM is that it's very easy to use. Everything is built-in, even when writing command lines."
"The performance is great."
"The key aspect is that the KVM directly interacts with the Kronos. There's no clear indication of indirect communication with Kronos. It is not linked to Kronos, and interaction is straightforward without any intermediaries."
"The initial setup was simple."
"It is a stable solution...It is a scalable solution."
"There aren't any bugs on the solution."
"The solution makes migration easy."
"It's a scalable solution."
"Stability and speed are the most valuable aspects."
"The initial setup is fairly straightforward and well-documented. The process is very similar to its competitors. The success of your setup depends on how well you plan."
"The most valuable feature of this solution is the support portal."
"The most valuable feature of Red Hat Enterprise Virtualization is its pricing."
"Monitoring and resolution could be improved."
"The solution should be more user friendly. We are struggling with the command lines."
"The solution’s user interface could be improved and made more user-friendly."
"We are not getting good support from KVM, and it is not that user-friendly."
"I would like to see more focus on microservices and integration with Kubernetes or OpenShift."
"KVM is very difficult to manage and run on daily operations."
"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."
"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."
"I heard that there are big differences between Red Hat eight and seven, but it's still quite difficult for me to judge it. I found it a bit more difficult to manage than version seven, which was much easier. In term of features, though, it is still not yet clear which is better. I have no clear idea of which features need to be changed at the moment."
"The documentation is not as good as it should be."
"The solution could use network virtualization."
"With RHEV, the cyberattacks should be fewer. I want RHEV to be better protected."
"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."
"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."
