See the debugging section below and closed issues before opening a new issue.
Known to work on:
-
Ubuntu 15.10 running on i5-6500 CPU.
-
Ubuntu 16.10 running on i7-3960X CPU.
-
Fedora 24 running on i5-6500 + i7-6600U CPU.
Tested with QEMU 2.4.1, 2.5, 2.6.1, and 2.8.
AMD CPU(s) are known to be problematic. AMD FX-8350 works but Phenom II X3 720 does not. A CPU with SSE4.1 support is required for macOS Sierra.
Intel VT-x / AMD SVM is required.
-
Download OS X El Capitan or macOS Sierra installer from Apple App Store.
-
Clone this repository. Files included in this repository are needed for ISO creation.
git clone https://github.com/kholia/OSX-KVM.git -
Run the ISO creation script
create_install_iso.shincluded in this repository. Run it withsudo.This script supports specifying the path to OS X / macOS installation application manually via the
-aoption. -
Copy the generated ISO from your Mac to your QEMU/KVM machine.
-
Clone this repository again on your QEMU system. Files from this repository are used in the following steps.
-
Install QEMU and other packages.
sudo apt-get install qemu uml-utilities virt-manager -
See networking notes to setup guest networking.
-
Create a virtual HDD image where the OS X operating system will be installed. If you change the name of the disk image from
mac_hdd.imgto something else, the boot scripts will need updating to point to the new image name. A base install of OS X needs 10 GiB of space. Adding Xcode or other large software obviously increases that requirement.qemu-img create -f qcow2 mac_hdd.img 64GNow you are ready to install OS X / macOS.
To install OS X, you can use the included boot-macOS.sh script for a more
solid alternate to the following virsh method. Use either the boot-macOS.sh
method or the following virsh method to install OS X / macOS.
-
Edit
macOS-libvirt.xmlfile and change file paths formac_hdd.qcow2(HDD),Install_OS_X_10.11_El_Capitan.iso(bootable ISO image) andenoch_rev2839_bootsuitably. -
Create a VM by running the following command
virsh --connect qemu:///system define macOS-libvirt.xml
-
Start the VM in virt-manager and hit return in the console window.
-
After booting, the initial language selection should show up.
-
... and initialize the new harddisk. If this step fails and the menu bar shows "Language Chooser" then see the Debugging section below.
-
After disk initialization, open a terminal window (in the Utilities menu) and recursively copy the /Extra folder to the newly initialized target volume using
cp -av /Extra "/Volumes/NewVolumeName" -
When finished, the VM will reboot automatically and the first time setup continues as usual.
-
The
boot*.shscripts have the installation ISO listed in them but this is only required for installation. Once installation is complete, comment out the-deviceand-drivelines referring to MacDVD and the installation ISO. -
Inside the guest, you may modify the
/Extra/org.chameleon.Boot.plistfile to change the default resolution of the virtual screen. See notes for instructions on how to do this and some limitations on the resolution choices. -
Download a Chameleon wizard such as Chameleon Wizard or Champlist in order to generate a usable smbios.plist. This file goes into
/Extraand can be used to assign a reasonable serial number to your virtual Mac. Generating this file sometimes fixes software incompatibilities that occur when the software can't determine what Apple hardware it is running on. -
For better mouse behavior, install https://github.com/pmj/QemuUSBTablet-OSX and configure QEMU to use the "usb-tablet" absolute pointing device.
-
To get sound on your virtual Mac, see the "Virtual Sound Device" in notes.
-
For macOS Sierra change the CPU model from
core2duotoPenryn. Theboot-macOS.shscript already has this change. -
While booting from the macOS Sierra ISO installer, you might get stuck on the "Language Chooser" menu bar (with no option to launch Disk Utility). The solution is to use Ctrl+F2 and arrow keys to navigate the "macOS Installer" menu bar, and to launch the "Disk Utility".
An alternate solution is to type
Super-T(whereSuperis the Mac command/clover key next to theAltkey). Type this sequence multiple times until a terminal window opens up. In the termianl window type:diskutil listThis will generate a list of all attached disks. Look for the disk with a size similar to the
mac_hdd.imgcreated in an earlier step. Once identified, note the disk number. Run a command to initialize the filesystem.diskutil eraseDisk JHFS+ <name of disk> <disk#>For example:
diskutil eraseDisk JHFS+ SYS disk2Then select your language and click the forward arrow to move to the next step.
-
Host machine may need the following tweak for this to work,
echo 1 > /sys/module/kvm/parameters/ignore_msrs -
Type the following in the bootloader if the guest VM fails to boot (some older ISO images may require this),
"KernelBooter_kexts"="Yes" "CsrActiveConfig"="103" -
If you see "hdiutil: attach failed - Resource busy" error message during the ISO creation step, quit the "Install macOS Sierra" program and unmount (eject) the "Install macOS Sierra" device. Disk Utility can help for unmouting disk images.
$ hdiutil info $ hdiutil detach /dev/disk2 # or something similar -
If the App Store doesn't work, check the notes file for instructions on how to solve this.
-
If you are getting "Dont_Steal_MacOS" related errors, see
Building QEMU(recommended option) andFakeSMC installationsections in notes file. -
If the boot process is getting stuck on the Apple logo, upgrade your host kernel and QEMU. For example, Linux 3.16.x from Debian 8 is known to be problematic, whereas Linux 4.9.x with QEMU 2.8.x works fine on the same distribution.
