Mac OS 10.4 (PowerPC) in QEMU. Now that Apple has ended supporting PowerPC applications having Mac OS 10.4 around can be a life saver. With it you can continue to use your favorite PowerPC applications. Suggested command-line: qemu-system-ppc -hda -boot c -netdev user,id=mynet0 -device rtl8139,netdev=mynet0.

In fact runing virtual machines for development is pretty much essential for anything that is non-trival. For Mac developer, this meant a choice of VMWare or Parallels and now you can also use Linux with KVM / QEMU and Clover/OVMF. Here are the high level steps and instructions required to get macOS (OS X) up and running on Ubuntu with KVM / QEMU. Qemu emulator mac os x 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.

Running qemu on a linux platform means you have the ability to use hardware acceleration via KVM. This allows you to access the virtualization features of your processor. For MacOSX we aren’t as lucky since there currently is no port of KVM for MacOSX.

As of MacOSX 10.10 apple introduced hypervisor.framework which is their way of acccessing the virtualisation features of the processor. The downside to hypervisor.framework is it isn’t as readily supported in other applications such as Qemu. It also doesn’t have the ability to do nested virtualization which is important if you want to run something like EVE-NG.

Patched Qemu overview

There is currently work being performed to make a patch for Qemu here Patchew. The patch takes code from a modified version of a Qemu fork which is available here: Android Emulator. This code in turn was taken from a project called Veertu. Hopefully this project will be finished and make it upstream but for now, you can use the fork.

Installing patched Qemu

Download the code

The command below will download the code in to a locally directory called qemu.

Build and install the patched Qemu code

Next we can build the code.

In a new development uncovered by Qemu developer Gerd Hoffmann, Apple has apparently added early support for VirtIO and framebuffer graphics in a later Mac OS Mojave release.

These new Mac OS drivers (kexts) include support for stdvga and cirrus vga, to what extent still isn’t clear. What will probably be more interesting for passthrough users, though, is the addition of virtio-blk for disk passthrough and virtio-9p for drive sharing.

Mac OS Virtio is Here

In Hoffmann’s testing, both work with a little tweaking. He states that the virtio-blk driver only works in legacy mode, and the 9p share just needs to be mounted.

Clearly further testing is going to be needed to work out best practices and methodology, but it’s an extremely encouraging sign for those using Mac OS VMs daily.

Once we work out exactly how to support these features, it will mean better disk performance and more seamless host-guest communication.

Mac-OS-SimpleKVM maintainer Foxlet observed that this may be due to the re-introduction of rack mount mac pros, which would make perfect sense.

The high-spec models will be more than capable of advanced virtualization, so Apple is probably doing what they can to support that endeavor for customers. It may not be their intention, but this might also vastly improve quality of life for Hackintosh OS X VM users as well.

It’s still early days, so we may very well see increased VirtIO driver support in future releases. Networking might even be on the table. In the meantime, all we can do is wait and hope that new kexts keep rolling in.

We’ll continue covering this as the situation develops, and hopefully have a method for leveraging these changes soon. In the meantime, if any tinkerers want to test VirtIO, please let us know how it goes on our discord or in the comments.
