Boot a Real Mac OS-X Partition under Linux and VirtualBox - What Works

VirtualBox 4.0

Works (does something)

• Nat networking
• Safari (I have edited this post using Safari on the OS-X VM)
• iTunes (starts - that is all I have done)
• iPhoto (starts - that is all I have done)
• About
• System Preferences
• Finder
• Finder sees other SMB and AFS shares
• Shutdown (mostly) 
• 1 CPU runs flat-out - to 'fix' this I ran this command. When the VM is idle the host load is much reduced:

• sudo rm -fr /System/Library/Extensions/AppleIntelCPUPowerManagement.kext

• By removing /System/Library/Extension
• Calculator
• YouTube
• Sound - I have tried IntelHD/ALSA
• USB with VirtualBox extras
• Disk Utility
• Intel PRO/1000 MT Desktop (Bridged adapter, eth1)
• Time Machine backup to Time Capsule if a network bridge is available

Does not work (or I can't get it working)

• glxgears (X11 crashes repeatedly)
• Shutdown (rarely)
• V8 Benchmark runs too slow for Safari's liking
