Quotes From Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros
"What I like about this solution, is that it is easy to configure.""The feature that I like most is the versatility.""It's in English, so its exceptional qualities make the control environment more flexible, easier, more stable, and easy to recover after issues.""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.""The case fileserver on the web server is the most valuable feature.""It's scalable. Whenever we buy another product other than hardware, it's easily integrated into the virtualization software that we download.""Active Memory Sharing dynamically reallocates memory of running partitions based on changing workload demands. The memory for the pool is carved out from Physical memory and is made logical memory. The said memory is not available to be assigned to partitions as dedicated memory. A min, max and desired as well as weight is assigned to the memory of each lpar to help hypervisor make a decision in case a condition where priority is to be given to a certain lapr to use the memory form shared pool."

"Our production servers are running in Linux, and this solution supports that environment well.""Scaling the solution is easy. You just have to add more hardware.""I like that this is an open-source solution. It is very powerful, and it's easy.""The KVM service is well managed with a central policy interface.""If you prefer command-line, there are all kinds of command-line options.""It is easy to use, stable, and flexible. It is a pretty mature product, and it is faster than VirtualBox.""The GUI interface makes the management of KVM easier than ever before.""This solution is open source and easy to configure."

Cons
"The program has very limited solutions for the virtualization of containers""Any improvements that can be made in the interface will go a long way to helping us work better.""I would like for IBM to be more focuses on the cloud.""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.""The performance should be improved.""If it could actually virtualize the entire platform it might be better. If you're having more than one virtualization technology, maybe there's a way to actually have less - one technology to run the data center and maybe one special virtualization for power. If it integrated with other platforms more effectively it might be better.""A GUI version of VIOS would be a great plus for people moving from Intel-based hypervisors."

"Support for VF is needed, where you can, for example, export from VMware to KVM.""The solution should be more user friendly. We are struggling with the command lines.""The virtual manager and the graphical QEMU for KVM need some improvement.""The initial setup of this solution is more difficult than some of the competing products and it could be improved.""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.""Its resource usage can be improved.""Business continuity features need to be added.""There are some issues with the graphics and some software that is very complex."

Pricing and Cost Advice
"The price varies from case to case and you have to negotiate it for every project.""The license cost is bundled with IBM Power Systems as it is limited to RISC-based IBM systems only."

Overview
Power is server virtualization without limits. Businesses are turning to PowerVM server virtualization to consolidate multiple workloads onto fewer systems, increasing server utilization and reducing cost. PowerVM provides a secure and scalable server virtualization environment for AIX, IBM i and Linux applications built upon the advanced RAS features and leading performance of the Power Systems platform.
KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko.
