[ovirt-users] Importing An Ubuntu Disk

Hello, I was wondering if there is any way to import a disk image (qcow/qcow2) into an oVirt storage domain? I've tried v2v but it won't work because the image customization parts of it won't deal with Ubuntu, and I tried import-to-ovirt.pl but the disks it creates seem to be broken in some way that prevents them from booting when attached to a VM. I've seen some references to creating a pre-allocated disk of the same size and then using dd to overwrite the contents of it, but is there a better method? Or should I just import my existing VMs by booting off a system rescue CD and restoring backups over the network?
