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

Pros
I find the density of the product most valuable. It is density that a technologist can just assign page merging. This is what makes KVM one of the important players of the virtualization market.The initial setup was simple.It is an open ecosystem, and we see there is a benefit in open-source solutions.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.KVM has a rich options set which can be directly used or via wrappers, such as libvirt.If you are a Linux desktop user, KVM is the solution to go with if you have to start virtual machines with Linux or other operating systems with almost zero extra configuration needed.A very reliable solution which can be used for x86 architecture virtualization with reasonable overhead.

Cons
The stability of this solution is less than other products in the same category.The KVM tech support is really bad. They are not very responsive.We would like to have a software lifecycle solution included in this solution. We can handle the software needed for KVM, but also the software that we provide. A lifecycle component would be very beneficial.Technical support is not top-notch.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.

The most valuable feature is the cost; it is a free product.To subscribe to the paid version with support, it is approximately $6,000 per year.The pricing and licensing is so important. Customers do consider the price seriously.

Overview
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.

Citrix XenServer is an open source virtualization platform that manages server, desktop and cloud virtual infrastructures. XenServer is straightforward and quick to install. Even the most demanding workloads and automated management processes can take just a couple of minutes to virtualize. XenServer lowers IT costs and increases IT agility and flexibility.
