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 product is really good...One can get good performance because of kernel-based virtualization."
"The initial setup was simple."
"This solution is open source and easy to configure."
"The product's scalability is good...It's a very stable product."
"I have found KVM to be scalable."
"Documentation and problem-solving troubleshooting are the most valuable features. Performance (when fine-tuned and with "special" HW) is awesome, equal to or more than other enterprise closed-source solutions."
"KVM has a rich options set which can be directly used or via wrappers, such as libvirt."
"A very reliable solution which can be used for x86 architecture virtualization with reasonable overhead."
"It is a stable solution...It is a scalable solution."
"Red Hat is the most stable system."
"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."
"It is a scalable solution."
"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."
"There aren't any bugs on the solution."
"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 this solution is the support portal."
"Its resource usage can be improved."
"The main drawback in the solution is probably disaster recovery."
"Business continuity features need to be added."
"We would like to have a software lifecycle solution included in this solution. We can handle the software needed for KVM, but also the software that we provide. A lifecycle component would be very beneficial."
"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."
"We are not getting good support from KVM, and it is not that user-friendly."
"I have encountered difficulties in getting the tool's documentation."
"Monitoring and resolution could be improved."
"Customers are not aware of this solution, they can improve by providing more awareness and solution availability."
"Red Hat by itself is not scalable. But you can have third party add-ons like Ceph to make it massively scalable."
"The solution has a very small lifecycle."
"It lags behind in that you need to go to something like Fedora to get all the extra bells and whistles."
"While everything needs improvement in some way, I have no specifics."
"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."
"The Administration of the Oracle database and the SAP ERP needs improvement."
"Configuring the network interfaces is much better in Ubuntu and should be improved."
