I have a few old games from an old power pc mac that I would like to see if I could setup a virtual machine to run.  I know that QEMU  has support for emulating completely different architectures but am completely baffled on how to set one up.  I don't know if the QEMU binary for PPC emulation is included in UNRAID either.

Anyone ever played with this idea or know anything about it?

Would be cool to emulate MacOS 9.2 !

Would that be 32bit? 

This support was added in Unraid OS 6.11.1

Nice !

Did anyone tried it yet?

cant get it to work because qemu-System-PPC is still missing 🤔

Binaries are here, which version are you on?

All good on 6.11.5 for me.  Can't comment on earlier versions.

 

OK, following your commands in terminal I got the same result, the files exist. I was trying to navigate to usr/bin/qemu* with krusader docker before.

 

Trying to build a template. What am I missing here?

And if I try just ppc, I get this. 

Can you post your MacOS 9.2.2 XML configuration ?

How did you build this template ?

You need to change the emulator part in the XML to be the PPC binary.

 

  <on_crash>restart</on_crash>
  <devices>
    <emulator>/usr/local/sbin/qemu</emulator>

What do you suggest I change it to? If I try qemu-system-ppc it gives me no such file or directory error.

Here is my failed ppc XML. It is a heavily modified winXP template.

 

failed ppc.xml

UPDATE:

 

I got through the errors and was able to update the XML. However when I go to boot the machine this error comes up. Here is the current XML revision and error.

Almost booted.xml

Another step taken, New XML (removed CPU driver). A new issue.

 

 

master var store.xml

I am stuck here. Need to read up on how qemu uses openbios-ppc and why CLI under linux works but UNRAID template does not.

Have you tried using virsh to convert cli to xml?

 

domxml-from-native¶
Syntax:

domxml-from-native format config
Convert the file config in the native guest configuration format named by format to a domain XML format. For QEMU/KVM hypervisor, the format argument must be qemu-argv. For Xen hypervisor, the format argument may be xen-xm, xen-xl, or xen-sxpr. For LXC hypervisor, the format argument must be lxc-tools. For VMware/ESX hypervisor, the format argument must be vmware-vmx. For the Bhyve hypervisor, the format argument must be bhyve-argv.

 

I have not looked into that. It seems that this is something related to the nvram function where the VM wants to store variable data. I thought maybe the machine would create this file on first start up but so far no joy.

 

Would love to get more eyes on this, the last XML I posted has gotten me the closest. I am for now trying to use emaculation's posted QEMU 9.2.2 image. Tested the image to work under ubuntu with qemu-ppc installed.

Thank you, I looked at your XML template and you went much further than me. I thought there would have been a template for Mac OS 8 or 9 but probably everything has to be done or there is a rights problem. I will try to work on the subject but it is beyond my current skills.

I decided to build a real MacOS9 machine. Just ordered an Apple MDD DP1.42 machine to setup dual boot on 9.2.2/10.5.8

Might come back to this one day, but for now I will limit the VM's to Windows and Intel MacOS.

I have an Apple MDD MD 1,25 but I will use MacOS 9.22 on a VM for differents tests.

VMs configurations are not easy

This topic will still be followed...

This is my latest configuration. Manually added "pc-bios" folder from Qemu GitHub repository to "/usr/bin". But still no boot. "OpenBios" quotes "No valid state has been set by load or init-program". Tried it 1000x times with different configurations, read Libvirt references, used UTM configurations but I don't know what is missing 😕

(The image I'm using boots perfectly on Unraid when starting from shell)

./qemu-system-ppc -L /usr/bin/pc-bios -M mac99 -device VGA,edid=on -prom-env 'auto-boot?=true' -prom-env 'vga-ndrv?=true' -boot c -drive file=/mnt/user/isos/QEMUclean.img,format=qcow2,media=disk -drive file=/mnt/user/isos/Universal_Toolbox.toast,format=raw,media=cdrom -spice port=5900,addr=127.0.0.1,disable-ticketing

What error are you getting with this current configuration?

 

Nevermind, I re-read your post. So you are getting to openfirmware. That is further than me, ill see what I can do with this.
