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 most valuable feature of IBM PowerVM is the performance of the database workload."
"What I like about this solution, is that it is easy to configure."
"IBM PowerVM has the highest clock speed."
"The most valuable features in this solution are you do not get degradation in the performance like you could get in other solutions. There is a physical adapter that is better than a virtual one and you can assign adapters to a VM."
"The tool's performance is top-notch."
"Managing other operating systems is also straightforward with IBM PowerVM."
"The feature that I like most is the versatility."
"The case fileserver on the web server is the most valuable feature."
"A very reliable solution which can be used for x86 architecture virtualization with reasonable overhead."
"The GUI interface makes the management of KVM easier than ever before."
"I like that this is an open-source solution. It is very powerful, and it's easy."
"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."
"The initial setup was simple."
"The most valuable feature of KVM is its stability."
"It is an open ecosystem, and we see there is a benefit in open-source solutions."
"It is easy to use, stable, and flexible. It is a pretty mature product, and it is faster than VirtualBox."
"The solution should be advanced to fit with the container constantly."
"The program has very limited solutions for the virtualization of containers"
"To make it a ten, I would like for them to add automation and configuration tools in order to help use the manager."
"The interface is not user-friendly in places, so it could use some improvement."
"SRM for site recovery is a feature that should be included."
"The cost of this solution is high."
"Any improvements that can be made in the interface will go a long way to helping us work better."
"IBM should review the price of this solution in my opinion; it is too high."
"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 speed is around thirty percent slower than another competitor. This would be something to work on."
"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."
"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."
"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."
"The initial setup of this solution is more difficult than some of the competing products and it could be improved."
"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."
