I just had a look at my datafiles: - these are either 8gb (OS) or 250gb (LVM images) - can't mount those directly in my host OS (tried because of the next point) - I don't know to what VM this image/VM belongs . They're all quite the same (basic debian install), so determining it just by running strings etc on those will not be easy - I can't import the old VMs from the old storage. If I create new images and dd the old information into those new images the metadata will not be copied too. So the only option is not reusing the VM's but creating completely new ones and determining which disk images are required for these VMs. Then creating the new image structure and dd'ing the corresponding images from the old VMs into the new ones. In order to do so I need to know what data belongs to what VM. Is there a trick for doing this? I still do have the database from the old ovirt machine, this might save me. Will have a look into that one tomorrow. Cheers, Boudewijn
