Cannot use IDE bus when creating virtual machines for PPC64 architecture

[davidbitterlich]

Describe the issue
When I set up a new virtual machine for PPC64 linux, I can specify a iso file for boot and when I boot afterwards, I get the following error:
QEMU error: QEMU wurde mit folgendem Fehler beendet: qemu-ppc64-softmmu: -device ide-cd,bus=ide.0,unit=0,drive=drive68F9AC40-27FC-4F3C-8DE1-CC3F0E22AD8F,bootindex=0: Bus 'ide.0' not found
Because of #5735 I am unable to graphically change the disk type, so I need close UTM and edit the config.plist manually to change the type from IDE to something else.

For me it turned out that I need to use USB for CD drive and VirtIO for disks, but I'm not sure if that's the best solution. Why does UTM use by default IDE for both CD drive and disk drives if they do not play nicely together with QEMU?

Configuration

• UTM Version: 4.3.5
• macOS Version: 13.5.2
• Mac Chip (Intel, M1, ...): M2 Max
