[ovirt-users] Import VMs from disk

As I've described before I had issues with my deployment and had to recreate the engine. I never had a chance to export my VMs, but I did back up the files. Now I would like to import the old VMs into the new engine. Is there a way to 'slurp' in the old images ? I see different way to import from an export domain, form VMWare, etc., but I don't see a way to import directly from disk. Do I need to convert them ? To what and how ? Thanks,
