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.
"This solution is open source and easy to configure."
"The most valuable feature of KVM is its stability."
"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."
"It is an open ecosystem, and we see there is a benefit in open-source solutions."
"I have found KVM to be scalable."
"I like that it's easy to manage. It's also more powerful when it comes to security than others. That point of view is the one consideration. The other consideration is that it's cost-effective."
"The initial setup was very easy."
"The product's scalability is good...It's a very stable product."
"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."
"What they provide is way beyond the essential requirements of customers."
"Red Hat is the most stable system."
"It is a scalable solution."
"It is very stable."
"One of the most valuable features of this solution is the popularity of the OS."
"The solution is a great all-round product. The virtualization is especially good."
"There aren't any bugs on the solution."
"The solution’s user interface could be improved and made more user-friendly."
"Technical support could be better. In the next release, I would like to see an improved user interface and dashboard. This type of improvement will make it easy or help our engineers understand the solution from a requirement point of view."
"There are some issues with the graphics and some software that is very complex."
"In KVM, snapshots and cloning are areas where there could be a little more sophistication, like VMware."
"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."
"I have previously used VMware and KVM is easier to use. However, they both have their strengths depending on their use cases. They are mostly equal. One of VMware's advantages is it has better support."
"The speed is around thirty percent slower than another competitor. This would be something to work on."
"The availability of technical expertise with the solution may be limited in some areas."
"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."
"While everything needs improvement in some way, I have no specifics."
"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."
"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."
"The solution should be made more user-friendly."
"The Administration of the Oracle database and the SAP ERP needs improvement."
