This series makes it possible to use CD drives reliably with scsi-block. IDE and scsi-disk require more work, because the eject button is not usable.
CD drives are unmounted at VM start and opened exclusively. The locking state is saved and restored for extra kindness. However, drives are not remounted because they are unlikely to be needed in the host (they were CDs for a guest after all), and repeated close/open done by the block layer would turn into unreliable mount/unmount requests to udisks (unmounts after the first would return EBUSY).
