+This is a presentation given privately to the Red Hat KVM developers
+at the 2014 KVM Forum in Dusseldorf, covering the new technology from
+qemu that was used when writing virt-v2v.
+
+It is essentially a longer version of this blog posting:
+
+http://rwmj.wordpress.com/2014/08/29/virt-v2v-better-living-through-new-technology/#content
+
+For more information about virt-v2v, read the manual here:
