I have a collection of QEMU VMs for different CPU Architectures. In an attempt to fill in some gaps on architectures I lacked VMs for, I decided to spin up a PowerPC32 VM under QEMU. I chose Debian-PowerPC as the OS.
Install the prerequisite PowerPC packages:
# apt-get install qemu-system-ppc openbios-ppc
Download an image of the Debian PowerPC ISO DVD from https://cdimage.debian.org/debian-cd/current/powerpc/iso-dvd/
As of this writing the current version DVD ISO file name is debian-8.8.0-powerpc-DVD-1.iso and this is the filename we will use for the following examples.
Mount this ISO:
$ mkdir ~/powerpc-mnt
$ sudo mount /path/to/iso/debian-8.8.0-powerpc-DVD-1.iso ~/powerpc-mnt
You will need two files from this iso:
$ cp ~/powerpc-mnt/install/powerpc/initrd.gz ./
$ cp ~/powerpc-mnt/install/powerpc/vmlinux ./
Unmount the iso:
$ sudo umount ~/powerpc-mnt
Create the virtual disk:
$ qemu-img create -f qcow2 powerpc32.img 12G
Start up the QEMU VM with the iso attached as a usb device for installation:
$ qemu-system-ppc -m 1024 -boot d -hda powerpc32.img -initrd initrd.gz -kernel vmlinux -append "cdrom-detect/try-usb=true" -usb -usbdevice disk:/full/path/to/iso/debian-8.8.0-powerpc-DVD-1.iso -noreboot
Make sure you selected Guided - use entire disk when partitioning the hard disk. Do not use LVM.
When selecting packages, ensure ssh server is selected.
You will need the initrd.gz and vmlinux files from the powerpc32.img disk.
$ sudo modprobe nbd max_part=16
$ sudo qemu-nbd -c /dev/nbd0 armdisk.img
$ mkdir ~/qemu-mounted
$ sudo mount /dev/nbd0p2 ~/qemu-mounted
$ mkdir after-copy
$ cp ~/qemu-mounted/initrd.img-3.16.0-4-powerpc after-copy/
$ cp ~/qemu-mounted/vmlinux-3.16.0-4-powerpc after-copy/
$ sudo umount ~/qemu-mounted
$ sudo qemu-nbd -d /dev/nbd0

Note that these two files may have different names depending on the version of the kernel provided in your ISO. Look for files in ~/qemu-mounted with the same prefix as these files:
- initrd.img-3.16.0-4-powerpc
- vmlinux-3.16.0-4-powerpc
You are now ready to boot into the fully installed operating system. Use a command like the one below to boot:
$ qemu-system-ppc -m 1024 -hda powerpc32.img -initrd after-copy/initrd.img-3.16.0-4-powerpc -kernel after-copy/vmlinux-3.16.0-4-powerpc -append "root=/dev/sda3" -redir tcp:7777::22
To install packages via apt, you will need to edit /etc/apt/sources.list.
Make sure all sources referencing the cdrom source are commented out. These lines begin with deb cdrom:[Debian...
Uncomment out the last two lines of the file. They should be changed from:
deb http://ftp.debian.org/debian/ jessie-updates main
deb-src http://ftp.debian.org/debian/ jessie-updates main
To:
deb http://ftp.debian.org/debian/ jessie main contrib non-free
deb-src http://ftp.debian.org/debian/ jessie main contrib non-free
You should now have a fully functional PowerPC VM running Debian Jessie under QEMU.
Thanks for the guide, I also got PPC32 Qemu Debian running after following the description. Here are some status updates with Qemu 3.1 (under Windows 7 here):
The emulation of installation DVD media as USB storage is still necessary, otherwise install process hangs somewhere during basesystem unpacking. Btw the options have changed a little bit, as
-usbdeviceoption is obsolete. Making use of recently recommended qemu-xhci USB adapter:With options above,
-usbwould no more be necessary because that would add an extra USB bus.CD auto detection can probably be substitued by more straight forward
-boot das it's just a one-off process.Finally, for
-norebootoption, is it meant to be-no-reboot?
