[Qemu-devel] MacOsX 10.2 guest under a GNU/Linux host

[Jean-Michel POURE]

Dear friends,

I would like to install a MacOs X 10.2 guest under a GNU/Linux host.
Any sucess so far. How to proceed?

Cheers,
Jean-Michel

Well, to my knowledge, qemu doesn't yet have that ability. It doesn't 
currently (that I know of) have full-machine emulation capability for 
PowerPC, not to mention a compabile OpenFirmware implementation (and 
compatible OF drivers). I don't know if or when Fabrice intends to do 
something like that with qemu, and I don't believe the SheepShaver port 
is anywhere near far enough along (currently only OldWorld compatible, 
requires a ROM image, and last time I tried to build it, still slightly 
broken). If you have a PowerPC system, you can run MacOS X inside the 
Mac-on-Linux virtualization environment, which I've done on multiple 
occasions on my PowerBook Pismo, but that's about it. Also, Apple's 
licenses are written such that running their OS on non-Apple hardware is 
a direct license violation. Just FYI.

This is not legal in France:

As a basic principle of law, you shall be able to devide anything you buy for 
seperate use (even licenses).

This kind of license is not legal in most countries. I cannot tell about the 
US-American laws because I am not of American citizenship.

In my case, I bought a MacOsX 10.2 license for an old PowerMac in order to 
compile pgAdmin III (http://www.pgadmin.org). I never used the license 
because MacOsX 10.2 does not support Unicode.

So basically, I still have an old PowerMac with MacOs9 and an idle MacOsX 10.2 
license, which I would really like to use.

So, when Qemu or Balilik2 supports MacOsX 10.2 under a GNU/Linux host,
I am ready to make installation tests.

Cheers,
Jean-Michel

I tried OpenDarwin 1.4.1, 6.2 & 7.1 & GNUDarwin (version ?) for x86.
All load the kernel, start and seem to hang.
I can see the white screen with the Apple for all versions but 1.4.1,
then nothing more happens...

I work on PPC system emulation but I'm still far from running MacOS X
under qemu. The main reasons are:
- bugs in PPC emulation
- Lack of Open-Firmware: it did some tests with a quick hacked OF
emulation, but the good way is to wait for OpenBIOS to be available for
MacOnLinux (I did asked to have access to their sources, but for now
never got any answer, even to say "no !"). I may try to use the OF from
my Ibook to make tests, but this cannot be a solution for Qemu releases.
- Lack of hardware emulation: Mac is *NOT* great: the hardware
specifications change almost every day :-). For now, my goal is to
emulate the 3 PPC standards: PREP, CHRP and OpenPPC. Some Macs are quite
CHRP machines, newer ones seems more like OpenPPC ones.
For now, I use PREP, because my first goal is to eliminate PPC CPU
emulation bugs. As PREP is nearly a PC with a PPC CPU, I can re-use
current Qemu hardware emulation, which make things simpler...
The only thing I got for recent Mac emulation is OpenPIC (good start).

I don't intend to emulate oldworld Macs for now.
I'd better have a recent one working, because the hardware is more
standard and documented.

Current PPC system emulation status is:
I can launch Linux and a shell in it and use it. That's all.

All this need to be merged with latest Fabrice's commits before I can
send patches...

It never intended to emulate OSX as it's of different ABI than Classic. So 
far, only OS 8.6 is supported at most. The advantage of SheepShaver 
approach is it's simply faster.

It supports old-style NewWorld ROM images (up to 1.6 AFAIK), as available
on Apple's FTP site. Parcels based ones are not supported yet.

Actually, it depends on your compiler. Tried 3.2 -> 3.4, no problem so 
far on amd64 nor ia32. What are the issues you are facing?
