You don't get the full CD-ROM passthrough functionality with host_device. Specifically, if you eject the virtual drive, the physical drive will only be ejected with host_cdrom, and the same is true for lock_medium. I think we may also make an attempt at detecting physical media change ocassionally with host_cdrom, but I doubt that this is working reliably anyway (the driver function is .bdrv_is_inserted, so it would be polling rather than processing an event; and I'm not sure when it's called).
