You can refer to my previous post for setting up KVM.

[root@gauss ~]# virsh list

Migration Command :

[root@euclid ~]# virsh migrate --live veuler qemu+ssh://gauss/system

[root@gauss ~]# virsh list

QEMU Vs KVM :

QEMU provides virtualization purely by means of software, and can be used as a stand-alone package.

KVM--which stands for "Kernel-based Virtual Machine"--provides for hardware-assisted virtualization. It can only be used with newer processors, such as Intel Core 2's or more recent AMD Athlon64's. It must be used in conjunction with QEMU.
