[Qemu-discuss] Sparc/PPC

[rudi]

Hello,
I tried to emulate sparc architecture on a Debian Wheezy host. The guest 
system is also a Debian system (tried Squeeze and Wheezy). First I tried 
it with the version, that comes with Debian Wheezy. After failing to 
boot, I compiled the newest snapshot (1.5) and a version from git. 
Always the same Problem.
Also I wanted to boot a Debian guest for PPC, either no go. I would be 
very thankful if you could give me a hint...

SPARC:

I also tried to compile a new version of openbios from svn :

###Input
qemu-system-sparc -hda ~/sparcq -cdrom 
~/Downloads/debian-7.0.0-sparc-netinst.iso -boot d -bios emuofw.rom

###Output

qemu: could not load prom 'emuofw.rom'



PPC:

###Input
qemu-img create -f qcow ppc.img 3G

qemu-system-ppc -hda ~/ppc.img -cdrom 
~/Downloads/debian-7.0.0-powerpc-netinst.iso -boot d -nographic

Welcome to Debian GNU/Linux wheezy!

This is a Debian installation CDROM,
built on 20130504-15:53.


Press ENTER to continue, or press TAB for a
full list of options.


If the system fails to boot with a white screen
which doesn't go away, try:

install video=ofonly

The following desktop environments are available:
gnome, kde, xfce and lxde.  The default on this CDROM
is gnome.
If you prefer a different desktop, append
    "desktop=<your choice>"
e.g. to do an expert install with the xfce desktop
environment, type
    "expert desktop=xfce"
at the "boot:" prompt.
Welcome to yaboot version 1.3.16
Enter "help" to get some basic usage information
boot: help

Press the tab key for a list of defined images.
The label marked with a "*" is is the default image, press <return> to 
boot it.

To boot any other label simply type its name and press <return>.

To boot a kernel image which is not defined in the yaboot configuration
file, enter the kernel image name as [[device:][partno],]/path, where
"device:" is the OpenFirmware device path to the disk the image
resides on, and "partno" is the partition number the image resides on.
Note that the comma (,) is only required if you specify an OpenFirmware
device, if you only specify a filename you should not start it with a ","

To boot a alternative initrd file rather than specified in the yaboot
configuration file, use the "initrd" command on Yaboot's prompt:
"initrd=[name.img]". This will load the "name.img" file after the default
kernel image. You can, also, specify a different initrd file to any other
label of the yaboot configuration file. Just type "label initrd=[name.img]"
and the specified initrd file will be loaded.

To load an alternative config file rather than /etc/yaboot.conf, enter
its device, partno and path, on Open Firmware Prompt:
boot conf=device:partno,/path/to/configfile
.To reload the config file or load a new one, use the "conf" command
on Yaboot's prompt:
conf [device=device] [partition=partno] [file=/path/to/configfile]

If you omit "device" and "partno", Yaboot will use their current
values. You can check them by entering "conf" on Yaboot's prompt.
