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."
"The most valuable feature is the flexibility in terms of managing the hardware resources such as RAM, CPU, and the network."
"A valuable feature of PowerVM is a feature that is used for higher availability plus stream for posting, which is very useful. There's a flash copy feature which we are using. PowerVM itself, I know, helps us to control and manage our Oracle licensing compliance, since it is our hardware partitioning. This is very important. If you use VMware, there will be a licensing issue. This PowerVM is a hardware partitioner, which is very important for license compliance. We are happy with this solution."
"IBM PowerVM's most valuable feature is stability."
"The most valuable feature of IBM PowerVM is the performance of the database workload."
"Managing other operating systems is also straightforward with IBM PowerVM."
"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."
"Scaling the solution is easy. You just have to add more hardware."
"One of the best features of KVM is its user-friendly interface."
"The initial setup was very easy."
"The most helpful aspect of KVM is the fact that the interface is so minimal. It includes just what you need to set up the VMs and manage them, and it's very simple to do so."
"The performance is great."
"It is an open ecosystem, and we see there is a benefit in open-source solutions."
"Our production servers are running in Linux, and this solution supports that environment well."
"I have found KVM to be scalable."
"SRM for site recovery is a feature that should be included."
"The solution should be advanced to fit with the container constantly."
"The product's pricing could be less expensive compared to other competitors."
"The cost of this solution is high."
"The interface is not user-friendly in places, so it could use some improvement."
"The hardware licensing model could be improved because the licensing model is a bit different from the standard hardware procured."
"A GUI version of VIOS would be a great plus for people moving from Intel-based hypervisors."
"Any improvements that can be made in the interface will go a long way to helping us work better."
"The stability of this solution is less than other products in the same category."
"I would like to see more focus on microservices and integration with Kubernetes or OpenShift."
"We are not getting good support from KVM, and it is not that user-friendly."
"The main drawback in the solution is probably disaster recovery."
"Some things are pretty basic, and they could be more robust with more detail."
"The product must provide better performance monitoring features."
"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."
"KVM is very difficult to manage and run on daily operations."
