We performed a comparison between IBM PowerVM and KVM based on real PeerSpot user reviews.
Find out in this report how the two Server Virtualization Software solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."The tool's performance is top-notch."
"IBM PowerVM has the highest clock speed."
"The most valuable feature of IBM PowerVM is the performance of the database workload."
"We always recommend PowerVM to our customers; it is better than most solutions."
"Technical support is great."
"What I like about this solution, is that it is easy to configure."
"IBM PowerVM's most valuable feature is stability."
"It's in English, so its exceptional qualities make the control environment more flexible, easier, more stable, and easy to recover after issues."
"KVM has a rich options set which can be directly used or via wrappers, such as libvirt."
"Scaling the solution is easy. You just have to add more hardware."
"The product is really good...One can get good performance because of kernel-based virtualization."
"Our production servers are running in Linux, and this solution supports that environment well."
"The most valuable feature is hypervisor. I can host at the same time different operating systems in Linux Windows."
"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."
"One of the best features of KVM is its user-friendly interface."
"Good screen and keyboard sharing feature."
"The hardware licensing model could be improved because the licensing model is a bit different from the standard hardware procured."
"The cost of this solution is high."
"I would like for IBM to be more focuses on the cloud."
"The solution should be advanced to fit with the container constantly."
"Any improvements that can be made in the interface will go a long way to helping us work better."
"As understand it, IBM sells all its hardware to Lenovo, and only PCs servers are managed by IBM. It's uncertain how much longer IBM will continue in this way, especially with the current trend of transitioning from on-premises to cloud and hybrid models. The market is evolving. Given this market shift, it's essential to identify areas for improvement. IBM has introduced the PowerVM Series, including Linux, which is a positive step. However, customers are already moving towards x86 servers due to cost considerations. The cost of PowerVM compared to x86 servers appears to be a significant factor."
"The interface is not user-friendly in places, so it could use some improvement."
"The performance should be improved."
"The initial setup of this solution is more difficult than some of the competing products and it could be improved."
"There are some issues with the graphics and some software that is very complex."
"Its resource usage can be improved."
"The stability of this solution is less than other products in the same category."
"Monitoring and resolution could be improved."
"In our setup, we do not have any dashboards or orchestration, and it is hard to manage. We have 25 gig network cards, but the software driver we have only supported 10 gigs."
"Business continuity features need to be added."
"In KVM, snapshots and cloning are areas where there could be a little more sophistication, like VMware."
