This would involve just a single copy and is about the most efficient way of doing it (even using qcow2 or LUN clones / FlexClone is unlikely to be better). > If there is a more sensible way of doing this I would like to know !

As mentioned I could do it fine in Ubuntu 10.04 not > 12.04 - i.e do I need to recompile libvirt, etc ? $ virt-resize /dev/vg/lv_template /dev/vg/lv_new Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones virt-p2v converts physical machines to virtual machines.
