Installing Windows 8.1 as VirtualBox Guest (Error 0x000000C4)

A short reminder to myself of what to do to prepare VirtualBox guest VM for Windows 8.1 (or Windows Server 2012 R2) installation:

Determine VM name dedicated to Windows 8.1 installation:

cmd> "c:\Program Files\Oracle\VirtualBox\VBoxManage.exe" list vms

"WIndows8-64" {2962e10b-2168-4d0c-b4b0-b9b104b66661}

Turn on CMPXCHG16B CPU property for VM:
"c:\Program Files\Oracle\VirtualBox\VBoxManage.exe" setextradata "WIndows8-64" VBoxInternal/CPUM/CMPXCHG16B 1
