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.
"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."
"KVM has a rich options set which can be directly used or via wrappers, such as libvirt."
"It offers a high-availability environment."
"One of the best features of KVM is its user-friendly interface."
"The product's scalability is good...It's a very stable product."
"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."
"It is an easily scalable solution."
"It is easy to use, stable, and flexible. It is a pretty mature product, and it is faster than VirtualBox."
"Technically, the main reason why I'm using Red Hat is because of its stability."
"One of the most valuable features of this solution is the popularity of the OS."
"What they provide is way beyond the essential requirements of customers."
"It is easy to deal with when comes to application migration and its compatibility with the multiple component applications."
"The solution is stable."
"The solution has a good licensing module."
"The most valuable feature of Red Hat Enterprise Virtualization is its pricing."
"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."
"The virtual manager and the graphical QEMU for KVM need some improvement."
"Some things are pretty basic, and they could be more robust with more detail."
"Monitoring and resolution could be improved."
"The main drawback in the solution is probably disaster recovery."
"The grid interface of KVM needs improvement. It could be more beautiful, especially when compared to VMware."
"One thing that maybe could be improved is making it easier to scale. It needs to be more clear on how to scale the storage space for virtual machines."
"The product must provide better performance monitoring features."
"The stability of this solution is less than other products in the same category."
"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."
"This solution could be more secure."
"The solution has a very small lifecycle."
"We'd like it if it would be possible on Red Hat Virtualization to possibly connect two or three VMs to the same disk."
"Red Hat by itself is not scalable. But you can have third party add-ons like Ceph to make it massively scalable."
"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."
"While everything needs improvement in some way, I have no specifics."
"With RHEV, the cyberattacks should be fewer. I want RHEV to be better protected."
