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 valuable feature is hypervisor. I can host at the same time different operating systems in Linux Windows."
"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."
"I like that this is an open-source solution. It is very powerful, and it's easy."
"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."
"I appreciate the network passcode feature in KVM, as it provides a convenient way to manage DNS and cloud hosting."
"It is easy to use, stable, and flexible. It is a pretty mature product, and it is faster than VirtualBox."
"I think nine out of the ten supercomputers in the world use Linux KVM, so I think that attests to the fact that it is a scalable product."
"It is a stable solution...It is a scalable solution."
"The price is the solution's most valuable aspect. It's much cheaper than, for example, VMware."
"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."
"Stability and speed are the most valuable aspects."
"It is a scalable solution."
"Technically, the main reason why I'm using Red Hat is because of its stability."
"The solution has a good licensing module."
"The most valuable feature of Red Hat Enterprise Virtualization is its pricing."
"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 speed is around thirty percent slower than another competitor. This would be something to work on."
"Monitoring and resolution could be improved."
"The grid interface of KVM needs improvement. It could be more beautiful, especially when compared to VMware."
"Some things are pretty basic, and they could be more robust with more detail."
"I have encountered difficulties in getting the tool's documentation."
"Support for VF is needed, where you can, for example, export from VMware to KVM."
"The initial setup of this solution is more difficult than some of the competing products and it could be improved."
"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."
"The solution has a very small lifecycle."
"Customers are not aware of this solution, they can improve by providing more awareness and solution availability."
"We would like the dashboard feature of this solution to be improved, as it is not very detailed at present."
"It lags behind in that you need to go to something like Fedora to get all the extra bells and whistles."
"The UI should be more interactive with additional features."
"The documentation is not as good as it should be."
"The solution could use network virtualization."
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.
