I'm trying to install on VirtualBox using the Yosemite iso from this site. I followed this howto: http://www.macbreaker.com/2015/01/virtualbox-yosemite-zone.html. The VM crashes as soon as the grey splash screen comes up. Here's the virtualbox log: https://bpaste.net/show/353728833a6a. I also tried the mavericks iso and I get the same error. I tried on VMware and I get an error about the CPU being disabled by the guest. On QEMU I don't get any errors but it hangs right after the splash is shown. I also downloaded a Mountain Lion vmware image from somewhere else and it gives me the same result. I tried different VM settings and boot options and at one point it seemed to boot but it never loaded a GUI, just a terminal that showed syslogd messages.
My virtualbox version is 4.3.26.
QEMU: Tried 2.2.0 and 2.3.0
VMware Workstation version 10.0.3.1895310
Linux kernel version: 4.0.1 on Gentoo
CPU: AMD A4-1250 APU with Radeon HD Graphics
Video: Advanced Micro Devices, Inc. [AMD/ATI] Kabini [Radeon HD 8210]
RAM: 4GB (2 for the VM)
Network: Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter
