Media type can’t be set to cdrom

[qdljerry]

It seems that no one can change the media type to cdrom

[qdljerry]

There is a code in UTM/UTMQemuSystem.m
Line:254
removable ? @"cdrom" : @"disk"
It made the CD-ROM type change to the disk

[qdljerry]

So it’s impossible for users to import a ISO file and read it as a unremoveable device

What is the intended use case for a non-removable CD image?

[qdljerry]

There isn’t any help document to describe that cdrom can only use as removable devices.
Many users new to (especially from VMware etc.) will be puzzled. (Including me)
For them, they’ll never know this feature until they read the source code.

Eg.
#2415
In this situation his drive configuration
media=disk

#2409
Also the same problem

these show that users are unaware of these changes of feature cause some problems in using UTM
We should add some tips or just modify the code

I believe there is no use, but the UI is confusing people. Other VM apps don’t offer Importing an ISO as a non-removable drive at all, because it doesn’t make sense. The Drives configuration UI should be re-vamped IMO, and I’d happily do it when I have the time.
