As you know, PowerPC emulation of Mac OS/OS X is a pain in the butt. Sheepshaver only emulates up to Mac OS 9.0.4, while PearPC only emulates Mac OS X 10.1 and up.

While looking on the Internet to find a way to emulate those version in between, I came across "QEMU on Windows". Normally, this an Intel X86 virtualize program. However, on that same site is a version which virtualizesa PowerPC computer. This of course piqued my interest.

While looking around, though, my hope fell. QEMU PPC apparently wasn't designed to run Mac OS X. Rather, it's purpose is to run Linux PPC versions. I haven't confirmed ifMacOS/OSXwillactuallyruninQEMUalone,butitdoesn'tlooklikely.Ifyouwanttotry,goahead.

Despite this setback, I went on searching and found something very interesting. [url="http://"http://mac-on-linux.sourceforge.net/"%5b/url"]Mac-on-Linux[/url] is virtualization software that allows you to run Mac OS/OS X in Windows. According to the site, it can run the Mac OS 9 versions that can't be run by SheepShaver, and can theorectically run versions of Mac OS X under 10.0. The kicker is that this program requires a Linux computer running on a PowerPC processor. I again was set back, when I realized a plan so simple it might just work.

Using QEMU on Windows PPC edition running aligh Linux distro for PowerPC processors, it might just be possible to run Mac-on-Linux in that. One problem is that it may be quite slow. On the other hand, Linux distros tend to light on resources, and QEMU comes with several built-in features that speed up virtualization.

So could this be possible? Could we finally run Mac OS X experimental versions? Possibly. I will try it out for myself, but I recommend that everyone tries this out.

Not roundabout enough. You've gotta throw in some ways to make it more complicated.

And its going to be SUPA {censored} slow. Double virtualization...*snort*

double emulation would be slow... but what we are discussing here is virtualisation on top of emulation, which wouldnt be that bad. How about Mac-on-linux on top of PearPC?





.......or how about anyone interested gets a B&W for less than 20? surely thats easier?

Well since PearPC and QEMU PowerPC are both virtualization, it should be possible.

I would rather use QEMU PPC though; PearPC is buggy and doesn't have totally working sound, while QEMU has been in development for awhile and has sound among other things.

PearPC is really slow..super slow. I really do not expect double virtualization to be faster, in fact its going to be slower which defeats the objective anyway. It would be amusing to do but don't expect any real work from it.

Actually, PearPC is quite usable if you have a Core 2 based system. I ran panther on it, and it ran about the same speed as 10.4.1 Intel in VMWare. <.<

ok this is very convoluted, but I'm installing Panther on PearPC on Windows on VMware on Leopard on Macbook. I'll try Mac-on-Mac once I'm done, if I don't run out of RAM/CPU cycles hahaha

actually it runs pretty well, but I cant get any of the virtual networking devices to configure, so that way of doing things might be closed.....

You should run it from Native Windows for the best performance/compatibility. XD

hmmm, probably. All my native Windows machines are a lot slower than this Macbook though (old P3s). I could use boot camp I suppose, I'll try it later.

But even if PearPC ran quicker, it would still be limited to Mac OSx 10.1+.

My suggestion may allow us to at least run versions of Mac OSx, OS 9, and Rhapsody not supported by either Sheepshaver or PearPC.
