A few years ago IDC published this analysis of KVM. A lot has changed since then but it's fun to look back and read: http://www-03.ibm.com/systems/resources/systems_virtualization_idc__kvmforservervirtualization.pdf For example, it says KVM has opportunities in the cloud. Today KVM is the default and best supported OpenStack hypervisor. I would focus on more than just KVM (the hypervisor). Consider what sort of virtualization solution you need. Are you doing server consolidation inside your organization? Are you doing virtual server hosting? Are you doing virtual desktop infrastructure? Then look at the management tools and ecosystem for that problem space. It doesn't matter how good the hypervisor is if your management tooling is a pain to use or doesn't support the storage or networking architecture you use. Next, evaluate it. KVM is free, try it out, prove it works. At that point you'll know which choice is right for you. Stefan
