Red Hat has a nice utility that takes care of this automatically: http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Virtualization/chap-Virtualization-v2v-migration.html Regarding your doc: Use 'virsh dumpxml <vm_name>' to get the XML file of your Xen host. You can then edit the resulting file and use 'virsh define <xml_file>' on your new host instead of having to run through virt-install. You'll probably want to use virtio drivers if you are running RHEL on RHEL for your new KVM guest. (<target dev='vda' bus='virtio'/>). You'll see much better performance, do the same with the network driver (<model type='virtio'/>).
