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.
"Our production servers are running in Linux, and this solution supports that environment well."
"The GUI interface makes the management of KVM easier than ever before."
"If you prefer command-line, there are all kinds of command-line options."
"There is a strong emphasis on availability, and they have numerous API interfaces for distributed storage and the solution is quite known for its openness."
"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."
"The most valuable feature of KVM is its stability."
"The initial setup was very easy."
"The initial setup was simple."
"It is very stable."
"I can control and manage everything. I know everything that's cooking inside. This is the best part for me."
"This solution is very stable. Much more so than similar products."
"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."
"Red Hat is the most stable system."
"The most valuable feature of this solution is the support portal."
"It is easy to deal with when comes to application migration and its compatibility with the multiple component applications."
"It is a stable solution...It is a scalable solution."
"The networking with wireless devices needs improvement."
"Business continuity features need to be added."
"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."
"I have encountered difficulties in getting the tool's documentation."
"We are not getting good support from KVM, and it is not that user-friendly."
"KVM is very difficult to manage and run on daily operations."
"The main drawback in the solution is probably disaster recovery."
"The initial setup of this solution is more difficult than some of the competing products and it could be improved."
"Configuring the network interfaces is much better in Ubuntu and should be improved."
"With RHEV, the cyberattacks should be fewer. I want RHEV to be better protected."
"Customers are not aware of this solution, they can improve by providing more awareness and solution availability."
"We hope that Red Hat can produce a paradigm edition. We are looking for paradigm computing and paradigm storage. Its scalability can be improved. It is not easy to scale, and we hope that Red Hat can provide a more scalable system. They should also provide local service and support. Our customers are looking for a good software vendor to provide professional services."
"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 availability of technical expertise with the solution may be limited in some areas."
"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."
