Closing the drive tray will not automatically close the guest tray.  (It
doesn't now because of QEMU limitations---but if you open with no
physical CD-ROM, there's no hope of fixing it :)).

Ah, understood.  Was it stated in commit messages?

VMs with physical CD-ROMs in general should not be migrated, so I think
migration is not a problem in this case.
