VirtualBox Error 0x000000C4

November 21, 2013 5 comments

I recently tried to upgrade a Windows 8 VirtualBox virtual machine to Windows 8.1 and ran into an error during the process. If I tried to run the upgrade from within the operating system (which is the required way), I received an error stating that my system did not meet system requirements. Specifically it mentions that my processor does not support “CompareExchange128”. After doing some research, I figured out how to turn on support for that in VirtualBox.

In Linux type the following in a terminal:
VBoxManage setextradata [vmname] VBoxInternal/CPUM/CMPXCHG16B 1
NOTE: Be sure to replace [vmname] with the name of your virtual machine.

In Windows type the following in a command prompt:
"C:\Program Files\Oracle\VirtualBox\VBoxManage.exe" setextradata [vmname] VBoxInternal/CPUM/CMPXCHG16B 1
NOTE: Be sure to replace [vmname] with the name of your virtual machine.

This also affects individuals installing Windows Server 2012 R2 on VirtualBox.
