 ./configure --target-list=ppc-softmmu --enable-sdl && make

Mac OS X Server 1.2v3

Installation requires several steps. Only use an .img HD, qcow2 will not work:
Step 1: boot from installation CD, use disk utility to partition disk as Apple Server, start the installation and let it fail. Quit Qemu and reboot with command line in step 2.

 ./qemu-system-ppc -L pc-bios -boot d -M mac99,via=pmu-adb -m 256 -net none -prom-env "auto-boot?=true"  -prom-env "boot-args=-v" \
 -cdrom OSXServer1.2v3.iso -hda OSXServer1.2v3.img

Step 2: initial installation (note machine and CPU, otherwise no desktop is shown).

 ./qemu-system-ppc -L pc-bios -boot d -M g3beige -cpu G3 -m 256 -prom-env "boot-args=-v" -prom-env "auto-boot?=false" -net none \
 -hda OSXServer1.2v3.img -cdrom OSXServer1.2v3.iso

At the boot prompt enter "boot cd:9,\\:tbxi" Initial installation starts. Quit Qemu after completion.

Step 3: Installation continued. Boot with the following command line to complete the installation.

 ./qemu-system-ppc -L pc-bios -boot c -M g3beige -cpu G3 -m 256 -prom-env "boot-args=-v" -prom-env "auto-boot?=true" -net none \
 -hda OSXServer1.2v3.img -cdrom OSXServer1.2v3.iso

Step 4: Boot the installed system:

 ./qemu-system-ppc -L pc-bios -boot c -M g3beige -cpu G3 -m 256 -prom-env "boot-args=-v" -prom-env "auto-boot?=true" -net none \
 -hda OSXServer1.2v3.img -cdrom OSXServer1.2v3.iso

Pre-installed images of Debian 6 (Squeeze) and 7 (Wheezy) (both minimal and with desktop) can be found here: https://people.debian.org/~aurel32/qemu/powerpc/

These images boot with:

 ./qemu-system-ppc -L pc-bios -boot c -M mac99,via=pmu -m 1024 \
 -hda debian_wheezy_powerpc_desktop.qcow2 -g 1024x768x32

OpenSuse 11

Installing:

 ./qemu-system-ppc -L pc-bios -boot d -M mac99,via=pmu -m 512 -net nic,model=rtl8139 \
 -net user -hda opensuse11.qcow2 -cdrom opensuse11.iso -g 1024x768x16 

Once the license screen appears, press Ctrl-Alt-Shift-X to open a terminal. Follow https://en.opensuse.org/SDB:Install_openSUSE_on_an_Apple_PPC_computer to create partitions with pdisk. Write the map after partitioning and continue with Yast. Once Yast arrives at partitioning, select Expert partitioning, select the Hard disk and click Rescan disk.
Leave hda2 as it is.
Edit hda3 to format as Ext2, mount at /boot and set fstab option to: Mount in /etc/fstab by to Device Path (instead of Device ID)
Edit hda4 to format as Swap and set fstab option to: Mount in /etc/fstab by to Device Path (instead of Device ID)
Edit hda5 to format as Ext3, mount at / and set fstab option to: Mount in /etc/fstab by to Device Path (instead of Device ID)

Accept the partitioning and continue with formatting. Continue installing. There will be an error while the boot manager is being installed. Ignore it, do not retry and wait for the installation to finish and the system reboots. Quit Qemu at the openbios screen and edit your command line:

 ./qemu-system-ppc -L pc-bios -boot c -M mac99,via=pmu -m 512 -net nic,model=rtl8139 \
 -net user -hda opensuse11.qcow2 -cdrom opensuse11.iso -g 1024x768x32

Eyetech AmigaOne/Mai Logic Teron

The AmigaNG boards (amigaone, pegasos2, sam460ex) are primarily used for running Amiga-like OSes (AmigaOS 4, MorphOS and AROS) but these can also run Linux.

Eyetech AmigaOne/Mai Logic Teron (amigaone) The amigaone machine emulates an AmigaOne XE mainboard by Eyetech which is a rebranded Mai Logic Teron board with modified U-Boot firmware to support AmigaOS 4.

Emulated devices:

* PowerPC 7457 CPU (can also use``-cpu g3, 750cxe, 750fx`` or ``750gx``)
* Articia S north bridge
* VIA VT82C686B south bridge
* PCI VGA compatible card (guests may need other card instead)
* PS/2 keyboard and mouse

To boot, a modified U-Boot binary is needed. While released under GPL, its source is lost so it cannot be included in QEMU. A binary is available at https://www.hyperion-entertainment.com/index.php/downloads?view=files&parent=28. The ROM image is in the last 512kB of the file, which, on a linux host, can be extracted with the command:

 tail -c 524288 updater.image > u-boot-amigaone.bin

The BIOS emulator in the firmware is unable to run QEMU‘s standard vgabios so VGABIOS-lgpl-latest.bin is needed instead. This can be downloaded from http://www.nongnu.org/vgabios.

You can find some Linux images that work on the amigaone machine at the following link: https://sourceforge.net/projects/amigaone-linux/files/debian-installer/

Booting:

 ./qemu-system-ppc -machine amigaone -bios u-boot-amigaone.bin \
 -cdrom "A1 Linux Net Installer.iso" \
 -device ati-vga,model=rv100,romfile=VGABIOS-lgpl-latest.bin

From the firmware menu that appears select Boot sequence, Amiga Multiboot Options and set Boot device 1 to Onboard VIA IDE CDROM. Then hit escape until the main screen appears, hit escape once more and from the exit menu select either Save settings and exit or Use settings for this session only. It may take a long time loading the kernel into memory but eventually it boots and the installer becomes visible. The ati-vga RV100 emulation is not complete yet so only frame buffer works, DRM and 3D is not available.

aCube Sam460ex

Booting:

 ./qemu-system-ppc -machine sam460ex -rtc base=localtime \
 -drive if=none,id=cd,file=Sam460InstallCD-53.58.iso,format=raw \
 -device ide-cd,drive=cd,bus=ide.1

Xilinx Virtex ML507 reference design

 ./qemu-system-ppc -m virtex-ml507

Debugging tips

Command line options

 -d unimp,guest_errors

(logs unimplemented features and guest errors to stdout)

 -trace 'pmu_*'

(logs all PMU accesses to stdout)

 -trace 'usb*'

(logs all USB accesses to stdout)

Macsbug

Macsbug can be used with Mac OS guest to tell you what exactly stopped booting. The link for it is below.
Mac OS 9.2 comes with a built-in debugger. To use it, set the OpenBIOS variable “APPL,debug”:

Via QEMU's command-line options:

 -prom-env aapl,debug=2000000

In OpenBIOS type:
dev /
2000000 encode-int *Note: the number can be replaced with the many options available
“ AAPL,debug” property
then to boot from a cd type:
boot cd:,\\:tbxi

To boot from a hard drive image:
boot hd:,\\:tbxi

Debugging qemu-system-ppc with GDB on an x86 Linux host

To build gdb-powerpc-linux on Linux, you need the normal build tools such as GCC installed. Download the GDB source code. Version 7.9 is reported to work: http://ftp.gnu.org/gnu/gdb/gdb-7.9.tar.gz Unpack it and cd into the dir, then build and install with:

 ./configure -target=powerpc-linux --enable-sim-powerpc
 make && sudo make install

Launch qemu-system-ppc(64) with -s and -S. Qemu will pause and listen on port 1234 for GDB. Set -prom-env "auto-boot?=false" --nographic on the command line for the Qemu instance to be debugged.

 qemu-system-ppc -s -S -prom-env "auto-boot?=false" --nographic

Open another terminal and launch the GDB you just built:

 gdb-powerpc-linux
 target remote localhost:1234
 continue

You can set a breakpoint in GDB, like this:

 break *0x20dccc

Type "boot" in the terminal running Qemu.

Emulated hardware issues

Mac OS

-Only Mac OS 9.x support sound well. Use an experimental build.
-Mac OS 9.x will not boot with 64 Mb or less memory. They will also not boot with more than 1024 Mb.

How do I help

QEMU has many systems that can always be improved. Here is a brief list of possible areas you may want to work on:

• Documentation
• Testing
• Fixing operating system compatibility issues
• PowerPC emulation
• User interface
• OpenBIOS (firmware)
• Implement a 3D video card
• Improve various hardware (via-cuda, ata controller, etc..)

Knowledge in these areas could help:

• PowerPC Assembly
• 68K Assembly
• Embedded Programming
