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 most valuable feature is administration."
"It's in English, so its exceptional qualities make the control environment more flexible, easier, more stable, and easy to recover after issues."
"It is a complete solution."
"Managing other operating systems is also straightforward with IBM PowerVM."
"The stability is the most valuable aspect of this solution. IBM is the most powerful and stable platform."
"We always recommend PowerVM to our customers; it is better than most solutions."
"The product never fails to work and is very stable in general. Stability-wise, I rate the solution a ten out of ten."
"The case fileserver on the web server is the most valuable feature."
"I appreciate the network passcode feature in KVM, as it provides a convenient way to manage DNS and cloud hosting."
"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."
"Scaling the solution is easy. You just have to add more hardware."
"I have found KVM to be scalable."
"One of the best features of KVM is its user-friendly interface."
"The product is really good...One can get good performance because of kernel-based virtualization."
"KVM has a rich options set which can be directly used or via wrappers, such as libvirt."
"It is an easily scalable solution."
"I don't know whether this has been trialed already, but IBM should give us an alert when we reach seven or eight failovers so that we can automatically switch it to manual mode. That would be great because if we cross the 10-day licensing limit, we have to pay a hefty license cost to Oracle. If IBM could view that feature, it would be helpful in license compliance."
"Any improvements that can be made in the interface will go a long way to helping us work better."
"It is solely command-line based."
"The interface is not user-friendly in places, so it could use some improvement."
"I would like for IBM to be more focuses on the cloud."
"IBM should review the price of this solution in my opinion; it is too high."
"The cost of this solution is high."
"The solution is quite pricey."
"Support for VF is needed, where you can, for example, export from VMware to KVM."
"In KVM, snapshots and cloning are areas where there could be a little more sophistication, like VMware."
"Technical support is not top-notch."
"I would like to see more focus on microservices and integration with Kubernetes or OpenShift."
"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."
"The only negative aspect of needing hardware support is a fully functional KVM can be dropped. It would be nice if the support for other platforms, like ARM or Risk, were as good as the x86 one. However, with the democratization of Chromebooks based on these chips and mobile devices, it will not take long for that to happen."
"One thing that maybe could be improved is making it easier to scale. It needs to be more clear on how to scale the storage space for virtual machines."
"I have encountered difficulties in getting the tool's documentation."
