Just launch the 'QEMU - Mac OS 9.2.2.bat' (or 'QEMU - Mac OS X Tiger 10.4.11.bat') file and wait 30 seconds for Mac OS to boot up. Nevermind the yellow screen with a VRAM partition not found error, it will go past this without any problem. The Mac OS 9 package contains a 1GB disk image on which Mac OS 9.2.2 is already fully installed.

- 1QEMU on OS X (macOS) hosts
While QEMU's main host platform is Linux, it is also supported on operating systems for Apple's Mac computers (known as OS X or macOS). The official support policy covers the last two released versions of OSX; QEMU might work on older versions, but it is not guaranteed and it might not even compile on older versions.
Please note that fewer developers work on QEMU for Mac hosts, so it might be less stable (but I don't think it is). If you can replicate a bug on a Linux hosted QEMU before reporting it, this is helpful as it means a wider set of people might look into it.
Some system emulations on Linux use KVM, a special emulation mode which claims to reach nearly native speed.KVM is mainly used for x86 (32 and 64 bit) emulation on x86 hosts running Linux. Should you want to run Qemu with KVM support on a G5, depending on your distribution, you might have to compile your own kernel with KVM support.There exists a port of QEMU to Hypervisor.framework (a kernel module from Apple which is similar in spirit to KVM), but unfortunately it is not included in upstream QEMU.
- Copy the bootable.img file to your Server. Installing QEMU. We need to install qemu (the hypervisor), libvirt (the VM daemon), and virtinst (the VM manager). If you have Ubuntu = 19.10 or Debian = 10, then run the following: sudo apt install qemu-kvm libvirt-clients.

Building QEMU for OS X
The system requirements are:
- One of the last two most recent versions of OS X (currently that's 10.13 or 10.14)
- The clang compiler shipped with the version of Xcode for that OS X. GCC might also work, but we recommend clang
Additional build requirements are:
You may find it easiest to get these from a third-party packagersuch as Homebrew, Macports, or Fink.
After downloading the QEMU source code, double-click it to expand it.
Then configure and make QEMU. The target-list option is used to build only the machine or machines you want. If you don't specify it, all machines would be built. Probably not what you want.
This way doesn't require you to wait for the configure command to complete:
If your system has the 'say' command, you can use it to tell you when QEMU is done
You can use './configure --help' to see a full list of options.
Here are all the currently available machines:
- aarch64-softmmu
- alpha-softmmu
- arm-softmmu
- cris-softmmu
- i386-softmmu
- lm32-softmmu
- m68k-softmmu
- microblaze-softmmu

- sparc-softmmu
- sparc64-softmmu
- tricore-softmmu
- unicore32-softmmu
- x86_64-softmmu
- xtensa-softmmu
- xtensaeb-softmmu
We recommend building QEMU with the -default compiler provided by Apple, for your version of Mac OS X (which will be 'clang'). The configure script will automatically pick this.
Errors on old compilers
Note: If after the configure step you see a message like this:
you may have to install your own version of gcc. You can build it from source (expect that to take several hours) or obtain third party binaries of gcc available from Homebrew or MacPorts.
You can have several versions of GCC on your system. To specify a certain version, use the --cc and --cxx options.
Build with LLVM/Clang 7
If you need to compile with newer versions of clang (to get f.i. AVX/AVX2 support), you can install llvm through e.g., brew.
Note that building for machines with CPUs supporting such extensions will exclude running your binary on earlier machines.

This page documents how to create a hard disk image in QEMU.
The command[edit]
The standard command for creating a basic hard disk image is this.
It will create an output similar to this:
The command is broken down like this:
- qemu-img - This is the name of the program. It is necessary for using the following command.
- create - This tells qemu-img that we are creating a disk image. Other arguments include 'dd', 'info', 'map', 'measure', 'snapshot', 'rebase', and 'resize'. This will be described in more detail later on.
- -f - An argument that specifies which file format we are going to be using.
- qcow2 - The file format we are using, in this case qcow2. qcow2 is the recommended since it is dynamically allocated - e.g. it only allocates space when needed, but at a (pretty much) unnoticeable speed loss. There are many other file formats, which will be listed below.
- example.img - This specifies the name of the image we are going to be using. It can be whatever, and have whatever extension (or none at all), it doesn't matter.
- 100M - This specifies the size of the virtual disk. 100M stands for 100 megabytes. Of course modern operating systems take up much more than that, so it's recommended to make it at least 30 gigabytes or more, which can be done by replacing 100M with 30G. The following letters are excepted:
- K - K stands for Kilobytes. For instance, 100K would be 100 kilobytes. Unrecommended. You can create hard disk images in pure kilobytes if you wanted, e.g. 30000000k for 30 gigabytes.
- M - M stands for Megabytes. For instance, 100M would be 100 megabytes. You can also create hard disk images in pure megabytes if you want, e.g. 30000M for 30 gigabytes.
- G - G stands for Gigabytes. For instance, 100G would be 100 gigabytes.
- T - T stands for Terabytes. For instance, 1T would be 1 terabyte.
- P - P stands for Petabytes. For instance, 1P would be 1 petabyte. Unrecommended unless you happen to have a supercomputer handy.
- E - E stands for Exabytes. For instance, 1E would be 1 exabytes. Unrecommended unless you happen to have a supercomputer handy. Fun fact: The ext4 file system is capable of a maximum of 1.1529215 exabytes.
File formats[edit]
QEMU can recognize and read several different file formats, but this section will list the ones you can create with qemu-img.
qcow2[edit]
The recommended file format. It is fast, dynamically allocated, and has decent support in QEMU. However it does have a minor speed loss compared to raw, but this is unnoticeable in normal use.
qcow[edit]
This is an older version of the qcow2 file format. The main difference between the qcow2 and qcow file formats is that qcow2 supports multiple snapshots through a newer, flexible model for storing snapshots. It is recommended to use qcow2 instead.
raw[edit]
As the name suggests - it is a 'raw' file format, which means it will allocate all the space to the disk immediately, e.g. if you formatted a file named raw with 2G as the size, it would take up 2 gigabytes of space on the disk. This is the fastest option, and is recommended if you have a lot of disk space to spare.
vdi[edit]
A file format which is also compatible with VirtualBox 1.1. Recommended only if you are going to be switching through VirtualBox and QEMU frequently.
QEMU For Windows - PPC Emulator, Runs Mac OS 9.1, 9.2 + OSX ...
- static - If set, the image will be created with metadata preallocation.
vmdk[edit]
A file format which is compatible with VMWare 3 and 4. Recommended only if you are going to be switching through VMWare and QEMU frequently. It supports the following arguments:
- compat6 - Create a VMDK 6 image, instead of the default VMDK 4.
- hwversion - Specify the vmdk virtual hardware version. If set, the Compat6 flag cannot be enabled.
vpc[edit]
A file format which is compatible with Windows Virtual PC. Recommended only if you are going to be switching through Windows Virtual PC and QEMU frequently.
vhdx[edit]
A Hyper-V compatible image format. Not recommended unless you're going to switch between Hyper-V and QEMU frequently.
parallels[edit]
A Parallels compatible image format. Not recommended unless you're going to switch between Parallels and QEMU frequently.
file[edit]
Teach, Learn, And Make With Raspberry Pi – Raspberry Pi
Not a file with any format - just a plain raw file.
cow[edit]
Ancient, depreciated QEMU file format that is not present in newer versions. Like qcow2 and qcow, it is a dynamically allocated file format. This cannot be used in Win32. Not recommended.
Read only file formats[edit]
