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.
"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 have found KVM to be scalable."
"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."
"Our production servers are running in Linux, and this solution supports that environment well."
"What I like most about KVM is that it's very easy to use. Everything is built-in, even when writing command lines."
"A very reliable solution which can be used for x86 architecture virtualization with reasonable overhead."
"Scaling the solution is easy. You just have to add more hardware."
"I appreciate the network passcode feature in KVM, as it provides a convenient way to manage DNS and cloud hosting."
"This solution is very stable. Much more so than similar products."
"We find the ease of use of this solution to be invaluable. It is user-friendly and integrates well with other software."
"I can control and manage everything. I know everything that's cooking inside. This is the best part for me."
"The most valuable feature of Red Hat Enterprise Virtualization is its pricing."
"It is a scalable solution."
"The solution is overall very good with all the facilities. It is user friendly, easy to configure, has documentation, and support is available."
"Red Hat is the most stable system."
"There aren't any bugs on the solution."
"The product must provide better performance monitoring features."
"The stability of this solution is less than other products in the same category."
"I believe KVM offers a unified answer, while ProxMark addresses orchestration. KVM lacks orchestration. If the aim is to centrally oversee multiple KVMs – let's say to freeze them – a centralized management solution is absent."
"The initial setup of this solution is more difficult than some of the competing products and it could be improved."
"In KVM, snapshots and cloning are areas where there could be a little more sophistication, like VMware."
"Support for VF is needed, where you can, for example, export from VMware to KVM."
"The KVM tech support is really bad. They are not very responsive."
"Some things are pretty basic, and they could be more robust with more detail."
"With RHEV, the cyberattacks should be fewer. I want RHEV to be better protected."
"This solution could be more secure."
"The availability of technical expertise with the solution may be limited in some areas."
"There is not any proper documentation on the site to reference."
"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."
"The solution could use network virtualization."
