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 stability is the most valuable aspect of this solution. IBM is the most powerful and stable platform."
"It's in English, so its exceptional qualities make the control environment more flexible, easier, more stable, and easy to recover after issues."
"It's scalable. Whenever we buy another product other than hardware, it's easily integrated into the virtualization software that we download."
"The feature that I like most is the versatility."
"IBM PowerVM has the highest clock speed."
"The tool's performance is top-notch."
"Managing other operating systems is also straightforward with IBM PowerVM."
"It is a stable solution with reliable performance."
"I think nine out of the ten supercomputers in the world use Linux KVM, so I think that attests to the fact that it is a scalable product."
"The most valuable feature of KVM is its stability."
"The product's scalability is good...It's a very stable product."
"The product is really good...One can get good performance because of kernel-based virtualization."
"I appreciate the network passcode feature in KVM, as it provides a convenient way to manage DNS and cloud hosting."
"It is an easily scalable solution."
"KVM has a rich options set which can be directly used or via wrappers, such as libvirt."
"One of the best features of KVM is its user-friendly interface."
"IBM PowerVM does not integrate with Microsoft."
"I would like for IBM to be more focuses on the cloud."
"The program has very limited solutions for the virtualization of containers"
"This solution is lacking the ability to have servers act as a cluster, such as in VMware. IBM has come out with a feature similar to VMware's vCenter but it is not as mature. They need to add LPM shared-nothing feature, such as in vMotion."
"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 performance should be improved."
"The cost of this solution is high."
"IBM PowerVM could improve the price because it is expensive."
"Monitoring and resolution could be improved."
"I have encountered difficulties in getting the tool's documentation."
"The KVM tech support is really bad. They are not very responsive."
"The stability of this solution is less than other products in the same category."
"One problem I have is that it's not very scalable when it comes to resizing the VM disk dimensions. For example, if you have initially set a virtual drive to 10 GB and you want to upgrade it to 15 GB, it's not that easy."
"KVM is very difficult to manage and run on daily operations."
"There are some issues with the graphics and some software that is very complex."
"The product must provide better performance monitoring features."
