[Libguestfs] cdrom device handling

Is there a way for the tools to provide a configured cdrom as cdrom to the temporary guest? Right now both disk and cdrom retrived from libvirt will showup as disks in the temporary guest. This happens for bus ide and scsi. It seems on my test system the guest can not start from a scsi disk, but the scsi cdrom appears as scsi cdrom in the guest. So I think its maybe just a matter of generating '<disk type='file' device='cdrom'>' instead of '<disk type='file' device='disk'>'? I'm using this command, which works ok for me: virt-rescue -v -c qemu+ssh:///system -d opensuse12 -r Olaf
