What is KVM?

KVM (Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It allows you to run multiple virtual machines (VMs) with unmodified Linux or Windows images. Each VM has private virtualized hardware: a network card, disk, graphics adapter, etc.
