You also need to install new drivers into the guest, and make some other tweaks. It is much easier to use virt-v2v for this task, instead of trying to figure out all the pieces yourself. -- Eric Blake <a href="mailto:eblake@redhat.com">eblake@redhat.com</a> <a href="tel:%2B1-919-301-3266" value="+19193013266">+1-919-301-3266</a> Libvirt virtualization library <a href="http://libvirt.org" target="_blank">http://libvirt.org</a> </blockquote></div>
