AFAIK the additional ioctls for CD/DVD drives are not passed through from 
domU, and the size of the blockdevice is only determined once, while 
exporting it.

So basically it should work when there's a dvd/cd in the drive before starting 
domU, but changing the media and stuff like "eject", "lock tray" etc won't 
work.

So I think its much easier to mount it inside dom0 and export the filesystem 
as needed to domU, or simply copy all needed CDs into the domU filesystem.
