First, are you trying to boot a cdrom (cdr) where a hard disk is suppose to be? Also, are you trying to boot from cdrom or hda?

Try this if I'm guessing correctly.

Code:
qemu-system-ppc -m 1024 -M g3beige -hda Jaguar/Jauguar.img -cpu 7448 -boot d -cdrom Jaguar/osxdisk1.iso -prom-env 'boot-args=-v' -serial stdio

Hello,

Sorry, but not Jaguar/Jauguar.img and Jaguar/Jauguar.cdr (because image created in DiskUtility)
If you tell me how prepare good hdd image with qemu i'll be happy.
Also i reinstall my qemu with support sdl and vde and now, i see normal color for system... but can't boot from hdd, this error present, can't find video card.
Also try build qemu from git --HEAD, but not successful.


Code:
mpPro:PowerPC itux$ qemu-system-ppc -M g3beige -cpu G3 -m 1024 -sdl -hda Jaguar/Jaguar.vmdk -cdrom Jaguar/osxdisk1.iso -boot d -serial stdio  -prom-env 'boot-args=-v'


This image i see :)

Qemu has a utility for creating disk images, try this.

Code:
qemu-img create jaguar.img 4G


Then try again with the new disk image.

Not need use -sdl option, sdl used by default now :)

A MacOSX 10.2 kernel panic (system crash).

Maybe it is useful to repeat what you mentioned in your first post and what is again apparent form the appearance of the QEMU window in your images, that you run QEMU in OSX 10.10 (Yosemite) beta. Has anyone else had success running this in Yosemite beta?

Is that qemu OS9 emulation still under construction?

I think development has stalled.

perhaps... it has been a long time since it was announced

Re: GSOC qemu Boot Mac OS >= 8.5 on PowerPC system

So it seems that SheepShaver is the only choice to emulate OS 9 though it is not perfect now.
But I'm looking forward to the good news.

Re: GSOC qemu Boot Mac OS >= 8.5 on PowerPC system

GSOC was years ago now; unless we have some sort of coding revival, I don't see this moving anywhere any time soon. I was planning to look into this myself a few years back, but ran out of time to get both the OpenBIOS and the PMMU stuff running smoothly in qemu. So, for now, the focus is on improving MacII emulation via Mini vMac and Shoebill -- next up after that is getting PPC emulation improved in MESS and qemu, and then rolling all the fixes for those back into BII and SS at some point in the distant future :)

Oh yes…
The emulation code in SheepShaver is a bit too old: It won't compile on a Mac with Lion or later (GCC isn't included, and llvm-gcc won't compile it, and Clang doesn't like some ASM directives used by SheepShaver).

And to make matters worse, you can tweek the build so it doesn't use the asm that the newer tools don't like, but it expects to be able to map to location 0x00000000 in memory which newer OS X forbades (well x64 mode now, but that could extend to 32bit in the future).

It seems to me that the 0-map issue should be something we can overcome with a shim -- just point to a virtual address of 0, and let the OS dynamically reassign to wherever. Is there some reason this can't be done other than that nobody's spent the time and grief to implement it?

bump... http://wiki.qemu.org/Google_Summer_of_C ... _9_in_QEMU

Time for another kick at the can, it seems :)

[edit] and according to https://www.google-melange.com/gsoc/eve ... e/gsoc2015 tomorrow's the deadline if you want to sign up to work on it as a student :)

Alexander Graf, if you get a student for this, let us know... and there are a number of people on here who would be happy to help either mentor or student find resources etc. :)

What is the frequently used QEmu Disk format? QED or QCOW?

Thanks

Re: GSOC qemu Boot Mac OS >= 8.5 on PowerPC system

Wed May 27, 2015 7:32 pm

QCOW is severely deprecated; QCOW2 is the standard. It's the "QEMU copy-on-write format with a range of special features, including the ability to take multiple snapshots, smaller images on filesystems that don't support sparse files, optional AES encryption, and optional zlib compression."

Compared to this, QED is more lightweight, and runs at almost RAW performance levels, so is better when you want faster throughput. It contains support for backing files and sparse files, but doesn't have the extended feature set of QCOW2.

I still use VMDK for some stuff too, as it'll run under pretty much any virtual machine out there. However, while compatible with VMWare and VirtualBox, these are slow, and can introduce data errors over time. Plus, they don't snapshot well.

That said,

http://wiki.qemu.org/Features/Qcow3

One COW to rule them all :)

Re: GSOC qemu Boot Mac OS >= 8.5 on PowerPC system

Thu May 28, 2015 3:55 am

Thanks adespoton for yours clarification! Maybe I will try to implement VMDK into PearPC. So PearPC will able to read QEmu's ppc VMDK images.
QED and QCow2 (and QCow3) is a geeky stuff. It will be hard to implement them on PearPC.

Thanks!

Re: GSOC qemu Boot Mac OS >= 8.5 on PowerPC system

Thu May 28, 2015 5:10 pm

Having vmdk support in ppc would be wonderful... that's the "transport image" of choice with all the stuff I do for work and play. PearPC currently has some interesting restrictions on disk image sizes though, due to how its virtual controller is written. So not all vmdk images would work in PearPC, but a PearPC vmdk should work anywhere else, including qemu.

It seems we get a new shot at running OS 9 in Qemu:

Great. Thank you for the piece of news.

Yep, I already see some progress in openbios:

Good news!

This year's (2015) GSOC has a nice little approved project, specifically for OS 9.
