ignore MSR readout on host by VM (as described by Gabriel):Д®cho 1 > /sys/module/kvm/parameters/ignore_msrs.

It might be enough to upgrade to Ubuntu 15.04 Vivid Vervet which also contains QEMU 2.2. OSX started to boot but only showed a black screen after the kernel output. It appears that QEMU 2.1 in Ubuntu 14.10 is a little bit too old.

learn how to get the OSK string at Andrei's blog post.

copy chimera_4.1_boot bootloader file to Linux machine.

Qemu-img convert -f raw Yosemite.raw -O qcow2 mac_hdd_10.10.img VBoxManage clonehd -format RAW Yosemite.vdi Yosemite.raw

convert our VDI image from VirtualBox to RAW fomat:.

I used the new Ubuntu 14.10 Utopic Unicorn server variant which also features the OpenStack Juno release.

copy usr/standalone/i386/boot (the bootloader file) to chimera_4.1_bootДЄccording to Gabriel's requirements, we need a Linux machine with kernel 3.15+ and QEMU 2.1+.

extract the contents of chimeraV41.pkg to a new folder.

I tried Chimera as it seemed to be the most advanced variant. There are different forks of Chameleon which support Yosemite. The cause for this was that the kernel in Yosemite now lives at /System/Library/Kernels/kernel. I found out that the Chameleon bootloader was not able to load the kernel from /mach_kernel. I had success with Gabriel's description for running Mavericks and tried the same approach with Yosemite: It didn't work in the same way. Somlo already did great work for running Mac OSX on KVM (see ) but didn't cover Yosemite so far.ДЄndrei Ostanin also wrote a nice post on how to run Mac OSX Mavericks on KVM (see ).

Now what if we would like to run a prepared VM on a Linux machine running KVM instead of VirtualBox? In the last post we set up a VM running Mac OSX Yosemite the help of VirtualBox. Update : I was able to run Yosemite after switching to QEMU 2.3 and Chimera 4.1.
