KVM is a complete Linux-based virtualisation solution launched in 2005. KVM is a fork of QEMU. In some cases, the source code for the two products is resynchronised.
Included in the mainline Linux kernel since version 2.6.2, KVM can run virtual systems under all the major OSs by simulating standardised hardware, and supports advanced functions like migration and detailed inspections of the VM's status.
KVM is distributed under the GPL.
