kvm-83-164.21.0.1.AXS3

KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware.
Using KVM, one can run multiple virtual machines running unmodified Linux or Windows images. Each virtual machine has private virtualized hardware: a network card, disk, graphics adapter, etc.
