Installing KVM

sudo apt-get install qemu-kvm libvirt-bin ubuntu-vm-builder bridge-utils virt-viewer

libvirt-bin provides libvirtd which you need to administer qemu and kvm instances using libvirt
qemu-kvm (kvm in Karmic and earlier) is the backend
ubuntu-vm-builder powerful command line tool for building virtual machines
bridge-utils provides a bridge from your network to the virtual machines
