But if I then load another ISO image file into the VM while the guest machine is running, DOS does not recognize that the disk has been changed. A call of

With real hardware, you would press a key on the drive and this would trigger an eject signal. This also gives MSCDEX and the CD-ROM drivers the signal that the CD-ROM media should be ejected. So that they unmount the medium and are ready to mount a new medium.
Does QEMU offer any way to replicate this behavior?
Or is there an eject command for DOS with which you can give the command to a real drive that the CD-ROM media should be ejected. At least there is something like this in Linux.
