20 You obviously know more about libvirt than I do, but I'm wondering about
21 that 'hd'. qemu knows enough to interpret Wilmer.qcow2 as the boot disk,
22 but maybe libvirt isn't that smart.
23
24 I'd maybe try using an explicit '-hda Wilmer.qcow2' in your original script
25 so virsh doesn't need to assume anything while converting it.
26
27 Fingers crossed :)
