Kernel-based Virtual Machine

In computing, Kernel-based Virtual Machine (KVM) is a virtual machine implementation using the operating system's kernel. This often allows for greater performance than when using virtual machine solutions which rely on user-space drivers. For the sake of this article, KVM will refer to the Linux kernel virtualization infrastructure. KVM supports native virtualization on x86 processors that provide Intel VT-x or AMD-V extensions but does not depend on it; it has also been ported to S/390,[1] PowerPC,[2] and IA-64, and an ARM port is in progress.
