Libvirt is a library API providing the ability to manager a number
of virtualizaton technologies, including Xen, QEMU, KVM, VMWare,
etc.

QEMU is a virtual machine  & CPU emulator. KVM is a kernel hypervisor
providing hardware acceleration for QEMU virtual machine CPUs. Virtio
is an accelerated I/O layer for disk, networking & other misc devices.

Daniel
