Download "Ubuntu Virtualization Made Easy"

Ubuntu 12.04, the latest version of Ubuntu Server, has been designed to help you deliver new services faster and with more flexibility. The default virtualization technology supported in Ubuntu is KVM (Kernel-based Virtual Machine), a technology that takes advantage of virtualization extensions built into Intel and AMD hardware.

The KVM is a part of the Linux kernel. KVM needs a second layer to run in user space. This is much faster than running the entire virtualization process in user space, on top of another operating system. KVM is designed for use on processors that have either the VT-x or AMD-V extension enabled. Managing VMs with KVM in Ubuntu is done using libvirt and QEMU.
