Windows 8.1 in Virtual Box
I was attempting to run the Windows 8.1 Preview in a VM using Sun's Oracle's Virtual Box on a Windows 7 host. I ran into a minor problem.

The OS wouldn't boot. I received an error stating:

Your computer needs to restart. Please hold down the power button. Error Code: 0x000000C4 Parameters: [redacted]

Looking for the error code online led me to this article describing the issue and a fix. The key to fixing this was running the command:

"c:\Program Files\Oracle\VirtualBox\VBoxManage.exe" setextradata "" VBoxInternal/CPUM/CMPXCHG16B 1

The CMPXCHG16B is an instruction in 64-bit X86 processors that allows for atomic operations on octal words.
