Qemu Kvm Mac

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.

QEMU can emulate several types of VGA card. The card type is passed in the -vga type command line option and can be std, qxl, vmware, virtio, cirrus or none. With -vga std you can get a resolution of up to 2560 x 1600 pixels without requiring guest drivers. This is the default since QEMU 2.2. QXL is a paravirtual graphics driver with. The QEMU PC System emulator simulates the following peripherals: -i440FX host PCI bridge and PIIX3 PCI to ISA bridge-Cirrus CLGD 5446 PCI VGA card or dummy VGA card with Bochs VESA extensions (hardware level, including all non standard modes).-PS/2 mouse and keyboard-2 PCI IDE interfaces with hard disk and CD-ROM support-Floppy disk.

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.

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.

Binary Drivers

Binary drivers are provided by some Linux distributions including WHQL Certified drivers.

For example the binary drivers for Ubuntu can be found here.

64-bit versions of Windows Vista and newer (this currently includes Windows Server 2008, Windows 7, Windows 8, Windows Server 2008 R2 and Windows Server 2012) require the drivers to be digitally signed to load.

If your distribution does not provide binary drivers for Windows, you can use the package from the Fedora Project. These drivers are digitally signed, and will work on 64-bit versions of Windows:

• Drivers should be signed for Windows 64bit platforms.
• Here are some links how to self sign and install self signed drivers:
