What is KVM and what does it mean for Linux?
Kernel-based Virtual Machine (KVM) is an open source virtualization technology built into Linux ®. Specifically, KVM lets you turn Linux into a hypervisor that allows a host machine to run multiple, isolated virtual environments called guests or virtual machines (VMs). KVM is part of Linux.
