Removable USB Drives are always CDROM

[pmsjt]

Describe the issue

When adding a removable, USB Disk image, UTM still passes a CDROM parameter to QEMU.

In other words:

		<dict>
			<key>Identifier</key>
			<string>2E751467-FB9D-4548-9242-0C2DEE3DC342</string>
			<key>ImageType</key>
			<string>Disk</string>
			<key>Interface</key>
			<string>USB</string>
		</dict>

Results in

-device usb-storage,drive=drive2E751467-FB9D-4548-9242-0C2DEE3DC342,removable=true,bootindex=1,bus=usb-bus.0 -drive if=none,media=cdrom,id=drive2E751467-FB9D-4548-9242-0C2DEE3DC342

Note the media=cdrom parameter.

Configuration

• UTM Version: Version 4.1.6 (75)
• macOS Version: 13.3
• Mac Chip (Intel, M1, ...): M1

That is intended (USB = USB removable CD drive). What purpose is there for a removable USB drive that cannot be achieved as a USB removable CD drive?

Erm... an USB thumbdrive for example? Something I can inject, write to and eject without having to reboot the VM. I am achieving this by adding custom QEMU parameters and using the QEMU console, but that defeats the purpose of using UTM.

I don't understand why you are closing this. This is clearly a UI bug. The UI has the option to create am external USB CD or disk but the setting has bo effect. Despite of what the user selects, the result is always CD. Some wires are crossed or cut here.

This is great @osy ! Can't wait to give it a try :-)
